Stroud Green, North London📍

Out with the outdated aluminium, in with the timeless timber 👌🏽

Swipe to see how we restored this North London property back to its authentic heritage roots.

We stripped the original box frames down completely and upgraded them with our bespoke, double-glazed timber sashes in premium hardwood.

✨The standard features you get with us:

✅ Signature draught-proofing for year-round comfort.

✅ Heritage ironmongery for that flawless period look.

We didn’t stop at the windows. We also manufactured and installed a bespoke Accoya®️ door set featuring:

✅ Dual-colour paint finish.
✅ Reeded glass for privacy and style.
✅ Hardwood sill & heritage ironmongery.

Hot weather got you in a bother? 🥵

Let LSWD take care of the problem 👌🏽

When the sun beats down on a traditional bay window, period homes can quickly turn into greenhouses.

For this recent project in N2, we installed a complete premium replacement designed to handle extreme weather all year round.

Our high-performance features do more than just block out winter drafts—they are your best defense against summer heatwaves:

✅Advanced Double Glazing: Reflects external solar heat to keep your indoor spaces noticeably cooler.

✅Full Draughtproofing: Seals your home tightly, keeping hot air out and trapping refreshing air-conditioned or cooled air inside.

✅Premium Ironmongery: Allows you to securely lock your sashes partially open for safe, breezy ventilation at night.

✅Sikkens Spray Finish: Elite UV and weather protection that prevents warping, blistering, or fading in intense sunlight.

✅Bespoke Curved Tops: Perfectly preserved historical architecture, engineered with modern climate comfort.
