Conversions - General- 1 Dec 2025
They carried out a full ground floor renovation: full plumbing (including water and heating), rewiring, plan reconfiguration including change of load bearing walls, kitchen and bathroom fitting, tiling, plastering, painting. Restoration of parquet flooring due to change of floor layout, internal door frames and doors installations. Minor related repairs on the first floor: radiator replacement, creating more space for stairs. Progress remained steady and well-managed throughout. Team was autonomous (like checking with structural engineer/architect/building regulations without our involvement), and if the input was required due to insufficient details/designer solutions we were involved as expected (as we wanted). The project stayed broadly within the agreed budget and time. The slight overrun was related to an additional foundation needed, which was not planned initially. Need for additional foundation was due to structural engineer calculations and building control.

Conversions - General- 22 Nov 2020
We are very very happy with the job that Stuart and his team did. The job was completed on schedule and this was including a few extras I had asked for at the very last minute. The work has been done to a very high standard throughout- we have been so impressed with the quality of finish and attention to details. Stuart was also very communicative throughout - checking details with me on how I wanted things- things I wouldn't have thought to ask about. They were also respectful and careful with our belongings- covering things up where they could and deftly working around things that couldn't be moved. I would have no hesitation in recommending Pierce Construction to anyone looking to get building works done and they would be my first choice for any future building needs I might have.

Conversions - General- 29 Sep 2022
The job - gutting our living room. Tearing down the ceiling, removing all old wallpaper and ripping up the floor in order to insulate and add lighting. While we were doing this, we decided to replace the main steel in the living room (which was oversize and impacted the floor height in the guest room) and do remedial works in the guest room. The steel replacement was not time budgeted, but Oli and Tony didn’t hesitate to quote,To make time for us and bring in the structural engineer. Probably added 3 weeks to their time on site. The trades they brought in (plumbing for heating, electrician for downlighters, structural engineer and plasterers) were all professional, did an excellent job and were all unfailingly polite. It was easy to build a good, positive relationship with them, to the point we felt comfortable giving them the keys to the house so they could work while we went away for two weeks. They sent photos of their progress and showed up and worked as if we were there. I was very impressed by the state of the house when we got back. They watered our plants (I didn’t ask) and they cleaned the hallway so that it was spotless. They did a good job for a fair price, and were always cheerful and open to conversation. They came back to do a few snagging items without being chased (this is a huge thing for me, after having chased many builders to finish bits and pieces). I would definitely use them again.

Questions to ask local loft conversion companies in Windlesham

Choosing the right loft conversion company for your job requires finding someone who understands your home and your goals.

Find out which company can share your vision by asking the following questions:

What experience do you have with loft conversions in Windlesham?

A local loft conversion company in Windlesham will know the types of properties and building styles common in your area, as well as the planning and building regulations that apply. Ask about similar projects they’ve completed locally.

Are you insured, and do you offer a warranty for your work?

Insurance protects your home during the loft conversion process, while a warranty shows the company’s confidence in the quality and durability of their work.

How do you handle planning permission and building regulations?

Established loft conversion companies in Windlesham should understand local planning rules and building regulations. Ask how they’ll manage permissions, inspections, and compliance to avoid delays or legal issues.

What is included in your quote?

Ensure the quote covers all essential aspects of the loft conversion: structural work, windows or skylights, staircases, insulation, labour, and any additional fees. Understanding this upfront prevents unexpected costs later.

Do you manage the project from start to finish?

Some Windlesham loft conversion companies offer full project management, coordinating architects, builders, and tradespeople. Others may only handle part of the conversion. Clarifying this early on helps you understand what support to expect.

FAQ: Common questions about loft conversions in Windlesham

How long does a loft conversion take?

Typically, a loft conversion can take between 6 and 12 weeks, depending on complexity, planning permissions, and any structural work required. Be sure to discuss the timeline with any potential loft conversion companies in Windlesham before agreeing to start the work.

Do I need planning permission for a loft conversion in Windlesham?

Many loft conversions fall under permitted development, but some require planning permission, especially if you’re adding a dormer, extending the roof, or living in a listed building. A professional Windlesham loft conversion company can advise and handle permissions for you.

Will a loft conversion affect my home insurance?

Yes, you’ll need to update your home insurance to cover the conversion. Inform your provider about structural changes, additional rooms, and any changes to utilities or heating systems.

Can I stay in my home during the loft conversion?

Many loft conversions allow you to remain in your home, though noise and dust are inevitable. Some Windlesham loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
