Replacement Windows Glasgow — FAQs

Q1: How much does a single replacement window cost in Glasgow?

A standard white uPVC casement replacement window starts from around £700, which includes the window unit, professional installation, and removal and disposal of your old frame. Prices increase for larger windows, coloured finishes, or specialist styles like sliding sash.

Q2: What is the lead time for replacement windows?

From confirming your order to installation day, the typical lead time is 3 to 5 weeks. Every window is manufactured to your exact measurements, so there’s no off-the-shelf sizing — this ensures a precise fit and proper weatherproofing.

Q3: Will new windows increase my property value?

Yes. New energy-efficient windows improve your EPC rating and significantly boost kerb appeal — both of which are factors buyers and estate agents look at. Modern double glazing also removes a common negotiation point for buyers, which can help you achieve a higher sale price or a faster sale.

Q4: What happens to my old windows after removal?

We remove and dispose of all old frames, glass, and fixings as part of the installation. All waste is transported to a licensed recycling facility. You don’t need to arrange a skip or make any trips to the tip — it’s all included in the quoted price.

Q5: Can I replace timber windows with uPVC in my Glasgow tenement?

In many cases, yes. We install slim-profile uPVC sash windows that closely replicate the appearance of traditional timber sashes. If your tenement is in a designated Conservation Area (parts of the West End, Hyndland, Dennistoun, and others), there may be additional requirements around style and finish — we’ll check this for you at the survey stage.

Q6: Do I need to be at home during the installation?

Yes. We require an adult (18+) to be present to provide access and to sign off the completed work. At the end of the installation, our lead fitter will walk you through the operation of your new windows and confirm you’re happy before leaving. We don’t necessarily need you there the entire time but for access, sign off and showing you how the windows work we need you there.

Q7: Is the quote you give me the final price?

Yes. Our quotes are fixed and include VAT, all materials, labour, and disposal of old windows. We don’t add extras after the survey. The price we quote is the price you pay, and it’s valid for 30 days.

Q8: Can you replace windows during winter?

Yes. We install year-round, including through the winter months. We work on one window at a time so each opening is exposed for the minimum possible duration — your home won’t get cold. Modern sealants and fixings are designed to cure in low temperatures.

Q9: What should I do to prepare for installation day?

We recommend clearing the area around each window — move any furniture, ornaments, or fragile items back by about a metre. Remove curtains and blinds if possible. Our team brings dust sheets and cleans up after themselves, but a clear workspace helps us work efficiently.

Q10: What if there's a problem after installation?

Call us directly. As part of your 10-year guarantee, we’ll send a fitter to inspect and resolve any issues. We don’t use a third-party call centre — you’ll speak to the same team that fitted your windows.

Q11: Do your fitters work for SRK directly?

Yes. Our installation teams are employed directly by SRK and are fully trained and vetted. We don’t sub-contract our main installations to third parties, which means we maintain quality control from survey through to completion.
