What are the benefits of replacing my windows and doors?
Upgrading your old windows and doors brings big advantages to any Stamford home. A-rated energy-efficient windows cut energy bills by improving thermal performance and reducing heat loss, keeping rooms warmer. Modern double glazing products also boost sound insulation, perfect for busy areas. Choosing new uPVC windows, hardwood windows, or bespoke aluminium windows enhances security standards with robust multi-point locks. Replacing external doors, from composite doors to aluminium patio doors, eliminates drafts and refreshes curb appeal. With a huge range of styles and colours, you can customise to suit your property, all backed by a 10-year guarantee.
How much do Stamford windows cost?
The cost of Stamford windows depends on the type of window, materials, and glazing. For example, uPVC windows are typically the most cost-effective, while bespoke aluminium windows or hardwood sash windows cost more. Our team offers a free, no-obligation quote tailored to your property’s needs — whether it’s in Stamford town centre, nearby villages like Uffington or Ryhall, or further afield across Lincolnshire, Cambridgeshire, and Leicestershire.
What’s the difference between double glazing and triple glazing?
Double glazing uses two panes of glass to reduce heat loss, while triple glazing adds a third pane for even better noise insulation and energy efficiency. Many Stamford homeowners opt for A-rated double-glazed windows, but we also offer triple-glazing options for homes facing busy roads or colder corners of Lincolnshire and beyond.
How long does it take to install new windows?
Installation times vary by product. uPVC windows and composite doors are typically installed within 4 weeks, while aluminium windows take around 4–5 weeks. Our bespoke hardwood windows have a 10–12 week lead time due to craftsmanship. Once your deposit is paid, we’ll confirm the exact installation time by email. Our professional window fitters ensure every Stamford window installation runs smoothly and with minimal disruption.
What guarantees come with your Stamford windows and doors?
All our work comes with a 10-year insurance-backed guarantee. Whether it’s composite doors, casement windows, or a full set of glazed windows, our Stamford customers enjoy peace of mind with every Aperture Window Group installation.
Do your windows help reduce energy bills?
Absolutely. Our A++ energy-efficient windows help cut energy costs by reducing heat transfer and improving thermal performance. Stamford homeowners typically see savings of up to £150–£200 per year compared to single glazing or older double glazing. With today’s energy prices, it’s one of the smartest upgrades you can make.

Thanks to Ben and the fitting team. Our builder recommended Ben and we were so pleased with his guidance and support. We really didn’t know what we wanted and he gave us 2 options with drawings. So pleased we went with the Patio Sliding door option. Really pleased overall.

We recently had a new front door fitted by Aperture and I couldn't be happier with the service. From the initial consultation through to installation, the team was professional, friendly, and highly knowledgeable. The fitters arrived on time, worked efficiently, and left everything clean and tidy. The quality of the door and workmanship is excellent, and it has completely transformed the appearance of my home. I would highly recommend Aperture to anyone looking for quality products and outstanding service.

I contacted Aperture Windows to supply and fit a broken port hole window whilst obtaining quotes from a selection of local window companies. Ben was the only person who was happy to do a site visit to do a thorough quote, very competitive pricing, excellent communication, everything done as specified and a lovely window fitter. I would highly recommend this company.
