What Marlow homeowners tell us.
"Insulated garden studio, fully wired, plastered and finished — six weeks from survey to keys. It reads as an extension of the house, not a shed."
"A 7m bifold set across the back of our Chiltern barn conversion. Faultless install, faultless finish. The traffic door is a small detail that we now use every day."
"Their surveyor drove out twice before we'd even signed anything. That's the level of care we hoped for and rarely find."

- Do you handle conservation-area planning in Marlow?
- Many of our Buckinghamshire projects sit within the Chilterns AONB or conservation areas. Our heritage flush casements and timber-effect finishes are frequently accepted where UPVC once wasn't. We prepare planning-ready drawings with matched sightlines, glazing-bar depths and hardware for Marlow projects that require them.
- What guarantee covers aluminium windows in Marlow?
- Every aluminium windows installation in Marlow is covered by our insurance-backed 10-year guarantee — parts, labour and finish. Aftercare is direct with the installing team, not a call centre.
- Can I see recent aluminium windows work near Marlow?
- Yes — we can share recent aluminium windows case studies from across Buckinghamshire, including projects in Marlow Bottom, Little Marlow and neighbouring towns. Ask your surveyor at the on-site visit.
- What thermal performance does aluminium windows achieve in Marlow?
- Energy-efficient aluminium windows installed across Marlow, Buckinghamshire achieve whole-window U-values of 0.9–1.4 W/m²K, with the exact frame and glazing specification confirmed after survey.
- When are aluminium windows the right choice?
- For contemporary properties, larger apertures and rear extensions, aluminium offers slimmer frames, more glass and a lifespan measured in decades. On smaller period cottages, uPVC or flush casements usually suit better; we advise honestly at survey.
- What colours are available?
- Any RAL. The most popular finishes are RAL 7016 (Anthracite Grey), RAL 9005 (Jet Black), RAL 7021 (Black Grey), RAL 9001 (Cream) and Bronze textures. Dual-colour (different inside/out) is available across the range.
- Do aluminium windows get cold or condensate?
- Modern aluminium uses a 34mm polyamide thermal break inside the frame which stops cold transfer. With warm-edge spacer bars and A-rated glazing, condensation and cold-frame feel are eliminated — performance rivals uPVC.
