What customers say — Windsor & nearby
★★★★★ 4.9 / 5 from verified customers
★★★★★

“We had a rear dormer conversion done last summer — extra bedroom and en-suite for our teenage daughter. Got three quotes through this site, saved around £4,000 compared to the first firm we spoke to. The specialist handled planning permission and building regs start to finish. Highly recommend.”

Sarah M. Windsor
★★★★★

“Hip-to-gable conversion on our 1930s semi. I was nervous about the planning application but the specialist I found here had done dozens in our street and knew exactly what to submit. Project came in on time at 10 weeks. The new master bedroom is brilliant.”

James R. Leeds
★★★★★

“L-shaped dormer on our Victorian terrace — created two rooms and a bathroom from what was a completely unusable loft. The comparison process gave me confidence I was paying a fair price. Building control sign-off came through with no issues. Absolutely transformed the house.”
