Question 1

How long has the company been established?

Accepted Answer

B&M Joiners was established in 1970, and Sash & Case Windows Direct is our specialist window division. With 55+ years of experience and more than 100,000 windows manufactured and installed, we are Edinburgh's leading sash & case specialists.

Question 2

What areas do you cover?

Accepted Answer

We cover Edinburgh city and surrounding areas. Our workshop is based at 13–15 Rodney Street in Canonmills, Edinburgh.

Question 3

Do you offer free estimates?

Accepted Answer

Yes — every estimate is free, with no obligation. You can request an instant indicative estimate online in under a minute using our estimating tool, or arrange a free site survey for a firm price.

Question 4

How energy efficient are your windows?

Accepted Answer

Our most popular Premium Engineered Redwood windows achieve a U-value of 1.2 W/m²K with double glazing, comparable to a high-performance new build window. Replacing draughty single-glazed sashes with our A+ rated double glazing can reduce heat loss through windows by up to 60%.

Question 5

How are your windows sustainable?

Accepted Answer

Sustainability runs through everything we do. We are Platinum accredited by Zero Waste Scotland, all our timber is FSC certified, and we offset our carbon footprint through The Great Reserve initiative — planting a sequoia tree, a symbol of strength and longevity, on behalf of our work.

Question 6

What is engineered timber, and how is it different from traditional timber?

Accepted Answer

Engineered timber is created by layering smaller pieces of wood with the grain running in different directions, then bonding them together. Compared to traditional solid timber it is significantly stronger and more dimensionally stable, with virtually no warping, twisting or shrinking, meaning your sashes glide smoothly year-round. We also pressure-treat our timbers to resist rot, decay and insects, and apply three layers of water-based microporous Sherwin-Williams paint or stain in factory-controlled conditions for a flawless finish.

Question 7

Why choose engineered timber over uPVC?

Accepted Answer

Properly maintained engineered timber windows last 60+ years, while uPVC typically lasts 10–15 years before discolouration forces replacement. Timber is a natural insulator and a renewable, FSC-certified resource — uPVC is a plastic-and-metal composite that's hard to recycle. Crucially, timber preserves the classic profile that Edinburgh's period properties were designed for and that conservation officers expect.

Question 8

How long do your windows last?

Accepted Answer

Lifespan depends on the timber and glass you choose: Single- and Double-Glazed Redwood windows last 30+ years, and our most popular Premium Engineered Redwood/Grandis Hardwood range lasts 60+ years with appropriate aftercare. All ranges include a paint finish guarantee — please follow the cleaning and maintenance guide we provide.

Question 9

Do you replicate original window designs?

Accepted Answer

Yes — we specialise in like-for-like replacement windows. Every sash is bespoke, made to measure, and we carefully replicate traditional features including astragal bars, horns, putty-line detailing and the original glazing patterns of your property.

Question 10

What glazing options do you offer?

Accepted Answer

We fit single glazed and standard double glazed windows. Double glazing keeps the traditional profile of original windows while delivering modern thermal performance.

Question 11

What colours can my windows be painted?

Accepted Answer

We offer a curated period-appropriate palette — including Brilliant White, Off White, Cream, Edinburgh Stone, Duck Egg Blue, Sage Green, Hunter Green, Edinburgh Navy, Graphite Grey and Classic Black — applied in three coats of Sherwin-Williams water-based paint. Bespoke colours including RAL and Farrow & Ball references are available on request, and we'll match your selection on the estimate form.

Question 12

Can I have different colours inside and outside?

Accepted Answer

Yes — we offer a dual finish on all replacement windows, allowing you to pick distinct interior and exterior colours so your sashes complement both your façade and the room they sit in. You can select dual finish directly in our online estimate; it carries a small surcharge to cover the additional masking and second-pass spraying.

Question 13

What guarantee comes with the paint finish?

Accepted Answer

Our three-coat Sherwin-Williams superior water-based paintwork is guaranteed for 10 years, contingent on following the care and maintenance guide we provide. We recommend a re-coat every 5 years to keep your windows looking flawless against Scotland's weather.

Question 14

What ironmongery and period features are included?

Accepted Answer

All our windows include traditional sash cords and weights, plus a choice of high-quality ironmongery: concealed trickle vents, astragal bars, pulley wheels, sash fasteners, simplex fittings, and sash lifts & rings. We can match period-authentic finishes for Georgian, Victorian and Edwardian properties.

Question 15

How long does installation take?

Accepted Answer

A typical installation of 4–6 windows takes 2–3 days. Each window is removed and replaced individually so your home is never left exposed overnight. We protect floors, furnishings and garden areas throughout the installation, and we leave your home clean and tidy when we finish.

Question 16

Will I need to move out during installation?

Accepted Answer

No. We work room by room, completing each window before moving on. Most customers carry on with their daily routine while we work. We seal each opening the same day, so your home stays warm and secure throughout.

Question 17

What guarantee do replacement windows come with?

Accepted Answer

All replacement windows include a 10-year workmanship guarantee covering manufacture, installation and paint finish. Glass units are guaranteed for 10 years against seal failure. We also provide a maintenance guide so you can maximise the life of your investment.

Question 18

Do your windows reduce street noise?

Accepted Answer

Yes — our double glazed replacement sash & case windows significantly reduce external noise. For properties on particularly noisy roads, a secondary glazing solution can reduce noise by up to 80%.

Question 19

Can you match windows to neighbouring properties?

Accepted Answer

Yes — we routinely match sash profiles, astragal patterns, horn details and colour to neighbouring properties and the wider streetscape. This is particularly important in Edinburgh's conservation areas and terraced streets, where consistency across the elevation is expected by planning officers.

Question 20

Do you remove and dispose of old windows?

Accepted Answer

Yes — removal and disposal of your existing windows is included as standard. We carefully remove each sash, frame and sub-sill, then responsibly dispose of all materials. Where possible, timber is recycled in line with our Zero Waste Scotland Platinum accreditation.

Question 21

What happens to the internal linings and plasterwork?

Accepted Answer

Our windows are designed for a clean fit within the existing stone or masonry opening, so internal linings and plasterwork are preserved wherever possible. In some older properties minor making good may be required, which we handle as part of the installation. We'll flag any anticipated plasterwork during the survey so there are no surprises.

Question 22

How do your windows perform in Scotland's weather?

Accepted Answer

Our windows are engineered specifically for Scotland's climate. Pressure-treated engineered timber resists moisture, and our three-coat Sherwin-Williams microporous paint system allows the wood to breathe while repelling water. Combined with modern draught seals and A+ rated glazing, our windows keep out wind, rain and cold far more effectively than the originals they replace.

Question 23

Can you repair just one window?

Accepted Answer

Absolutely. Whether you need one window repaired or a complete building's worth, no job is too small or too large. We treat every project with the same care and attention.

Question 24

How long do repairs typically take?

Accepted Answer

Simple repairs like sash cord replacement can often be completed within a day. More complex work including timber repairs may take 2–3 days depending on the scope of work.

Question 25

What types of sash window repairs do you carry out?

Accepted Answer

We handle every aspect of sash window repair: broken sash cords and chains, damaged or seized pulley wheels, rotten or decayed timber (sills, bottom rails, meeting rails, stiles), draughty windows needing new seals and draught strips, worn or missing ironmongery (fasteners, lifts, locks), windows that won't stay open or rattle in the wind, and full overhaul of sashes that have been painted shut.

Question 26

How much do sash window repairs cost?

Accepted Answer

Costs vary depending on the extent of work. A simple sash cord replacement typically starts from around £120–£180 per window. Timber splicing and rail repairs range from £200–£500 per window depending on the extent of decay. A full overhaul, including stripping, re-cording, draught proofing, timber repairs and repainting, is significantly less than full replacement. We provide free, no-obligation estimates for all repair work.

Question 27

Is it worth repairing old sash windows or should I replace them?

Accepted Answer

We always insist a replacement is better value in the long term. It depends on their condition. If the frames and sashes are structurally sound with localised decay, repair is possible. Original Victorian and Georgian timber is often superior to modern softwood and well worth preserving. If frames are extensively rotten, warped beyond adjustment, or you want to upgrade to double glazing, replacement may be the better long-term investment. We'll give you an honest assessment during the free survey.

Question 28

Can you repair rotten timber without replacing the whole window?

Accepted Answer

Yes — we use a combination of resin-based splicing and timber grafting to repair localised decay. Damaged sections of sills, bottom rails, meeting rails and stiles can be cut out and replaced with new timber that's carefully shaped, primed and painted to match the original. This approach preserves as much original fabric as possible, which is especially important for listed buildings.

Question 29

My windows are painted shut — can you free them?

Accepted Answer

Yes — this is one of our most common repair jobs. We carefully break the paint seal, strip the sash channels, ease the sashes, replace worn sash cords, fit new draught seals and lubricate the mechanism so your windows slide smoothly again. The result is fully operational windows with improved ventilation and fire-escape capability.

Question 30

Can you add draught proofing as part of a repair?

Accepted Answer

Absolutely — we strongly recommend it. When we overhaul a window we routinely fit modern brush-pile or compression draught strips to the sash channels, meeting rail and top/bottom rails. This can reduce draughts by up to 90% and noticeably improve the thermal comfort of the room. It's a highly cost-effective upgrade that most customers combine with cord replacement and re-glazing.

Question 31

Do you repair sash windows in tenement flats?

Accepted Answer

Yes — we carry out repairs in tenement flats across Edinburgh regularly. We work from inside wherever possible, and for upper floors we can arrange scaffolding or use rope-access techniques where required. We're experienced with factored buildings and can provide individual flat estimates or a combined stair estimate for communal repair projects.

Question 32

Will repairs affect my listed building or conservation area status?

Accepted Answer

No — like-for-like repairs using matching timber, glazing and ironmongery are generally considered permitted maintenance and do not require planning permission or listed building consent. In fact, keeping your original windows in good repair is exactly what conservation officers encourage. We'll advise if any proposed work crosses the threshold into alteration.

Question 33

Do you guarantee your repair work?

Accepted Answer

Yes — all repair work is guaranteed for 12 months covering materials and workmanship. Timber splicing and resin repairs carry a 5-year guarantee against further decay in the repaired area, provided the window is maintained in accordance with our care advice.

Question 34

Do I need planning permission to replace my windows?

Accepted Answer

If your property is in a conservation area or is listed, you may need planning permission or listed building consent. We have extensive experience navigating this process and can advise you on the requirements and help with the application.

Question 35

Can you work on listed buildings?

Accepted Answer

Yes — we have 55+ years of experience on listed buildings and within Edinburgh's conservation areas. We work closely with Historic Environment Scotland and the City of Edinburgh Council's conservation officers to ensure full compliance.

Question 36

What makes a sash and case window 'non-compliant' in Edinburgh?

Accepted Answer

In a conservation area or listed building, replacement windows must match the original in design, materials, glazing pattern, sightlines and operation. Common issues that make windows non-compliant include: uPVC or aluminium frames, modern double-glazed units with thick spacer bars, applied (stuck-on) astragal bars instead of true through bars, casement or tilt-and-turn mechanisms in place of vertically sliding sashes, missing or wrong horn profiles, and visible trickle vents on principal elevations.

Question 37

I've been served a planning enforcement notice — what do I do?

Accepted Answer

Don't remove anything yourself. Get in touch immediately and we'll arrange an urgent compliance survey, prepare the technical drawings and specification the City of Edinburgh Council requires, liaise with your case officer, and quote for a compliant replacement. We've worked through dozens of remedial cases across the New Town, Old Town, Stockbridge, Marchmont, Bruntsfield and Leith conservation areas.

Question 38

Will non-compliant windows affect a property sale?

Accepted Answer

Yes — non-compliant windows almost always show up on Home Reports and conveyancing searches, particularly for listed buildings. Buyers' solicitors routinely ask for evidence of Listed Building Consent, and unauthorised alterations can drive down sale prices, delay transactions and complicate mortgage approvals. Bringing windows back into compliance protects both the building's character and your equity.

Question 39

Can uPVC sash windows ever be approved in Edinburgh conservation areas?

Accepted Answer

In almost all cases, no. Both the City of Edinburgh Council and Historic Environment Scotland take a clear position that uPVC is not an appropriate material for traditional sash and case windows in conservation areas or listed buildings. The only authentic, conservation-acceptable replacement is timber, typically engineered redwood or hardwood, manufactured to match the original profile.

Question 40

What is the lead time for new windows?

Accepted Answer

Single-Glazed Redwood, Double-Glazed Redwood and Premium Plus ranges typically have a 12-week lead time as they are bespoke-manufactured to your exact specification.

Question 41

What is the typical process for replacement windows?

Accepted Answer

The process starts with a free survey, followed by a detailed estimate. Once accepted, we manufacture your windows bespoke in our workshop, then arrange installation at a time that suits you. From order to installation typically takes 4–12 weeks depending on the range you choose.

Question 42

Is secondary glazing a good option for listed buildings?

Accepted Answer

Yes — secondary glazing is one of the most listed-building-friendly thermal upgrades available. Because it sits behind your existing window and doesn't alter the external appearance, it's typically acceptable in conservation areas and listed buildings. It can reduce heat loss by up to 65% and external noise by up to 80%.

Question 43

What exactly is secondary glazing?

Accepted Answer

Secondary glazing is a discreet, independent window system fitted to the room side of your existing sash & case windows. It creates an insulating air gap between the original glass and the secondary panel, dramatically improving thermal and acoustic performance — all without altering or removing the original window.

Question 44

How effective is secondary glazing at reducing noise?

Accepted Answer

Secondary glazing is one of the most effective noise-reduction solutions available. The air gap between the original window and the secondary panel can reduce external noise by up to 80% (approximately 45 dB). It's particularly effective on busy Edinburgh streets, near pubs and restaurants, or properties close to flight paths — often outperforming replacement double glazing for sound insulation.

Question 45

How much heat does secondary glazing save?

Accepted Answer

Secondary glazing can reduce heat loss through windows by up to 65%. The trapped air gap acts as an insulating buffer, and when combined with low-emissivity glass the performance improves further. Many customers report a noticeable difference in room temperature and a measurable reduction in heating bills within the first winter.

Question 46

Will secondary glazing cause condensation?

Accepted Answer

When properly fitted with adequate ventilation, secondary glazing should not cause condensation problems. In fact, it often reduces condensation on the primary window by keeping the inner glass surface warmer. We ensure each installation includes appropriate ventilation — typically through discreet trickle vents or by ensuring the existing window's ventilation is maintained.

Question 47

Can I still open my original sash windows with secondary glazing fitted?

Accepted Answer

Yes — our secondary glazing systems are designed to be easily opened, removed or slid aside so you retain full access to your original sash windows for ventilation and cleaning. We offer vertical sliding, horizontal sliding, hinged and lift-out panel options depending on the window size and your preferences.

Question 48

Is secondary glazing visible from inside the room?

Accepted Answer

Modern secondary glazing is designed to be as discreet as possible. Slim aluminium or timber frames sit close to the reveal and are painted to match your interior. Most visitors won't notice it's there — and from outside the building, the original windows look completely untouched.

Question 49

How does secondary glazing compare to replacement double glazing?

Accepted Answer

Both are excellent solutions but suit different situations. Replacement double glazing offers the best all-round thermal performance and a completely fresh window system. Secondary glazing is ideal when you want to preserve original windows (especially in listed buildings), need superior noise reduction, or want a lower-cost thermal upgrade. Secondary glazing is also non-destructive and reversible, which appeals to many homeowners and is favoured by conservation officers.

Question 50

How long does secondary glazing installation take?

Accepted Answer

Installation is quick and minimally disruptive. A typical window takes 1–2 hours. Most rooms can be completed in a single day, and there's no scaffolding, no external work, and no mess. We survey, manufacture to measure, and install — usually within 2–4 weeks of your order.

Question 51

How much does secondary glazing cost?

Accepted Answer

Secondary glazing is typically 40–60% less expensive than full replacement double glazing, making it a very cost-effective thermal and acoustic upgrade. Exact pricing depends on window size, glass specification and frame type. We provide free, no-obligation estimates — you can request one online or book a site survey.

Question 52

Does secondary glazing improve security?

Accepted Answer

Yes — secondary glazing adds a second barrier that makes forced entry significantly more difficult. Our systems use toughened or laminated glass options and secure locking mechanisms. For ground-floor and basement flats in Edinburgh, this is a meaningful security upgrade on top of the thermal and acoustic benefits.

Question 53

Can secondary glazing be removed later without damage?

Accepted Answer

Yes — secondary glazing is a fully reversible installation. The frames are fixed to the timber reveal or sub-frame, not to the original window. If you ever decide to remove it (for example, if you later opt for replacement double glazing), the original window is left completely intact with only minor screw holes that are easily filled.
