Extensions- 14 Nov 2019
Bogdan himself is extremely knowledgable and his years of experience in industry is clear to see, which makes choosing him great value for money. Before and during the project he offered solutions that we hadn't considered and the would in fact save us money and be of benefit to us in the future. His team is punctual, reliable, diligent, speedy and clean! They take pride in their work which has led to a highly satisfactory work in the final build. Bogdan also has great connections to third parties (e.g. to flooring and curtains/blinds providers) which is very valuable, especially when trying to coordinate different aspects and timings of a full house redecoration. His quotes and payment structures are fair, clear and concise which is also very helpful. His communication is excellent too. All in all, Bogdan's great work took away a huge amount of stress during these projects. I would highly recommend Bogdan and his team for any prospective works someone is considering.

Carpentry- 10 Sep 2016
I'm just discovered that through some oversight I've neglected to leave feedback on this job - replacing an old garden pergola, quite a large one. Lucas and his colleagues did excellent work and we were very happy with everything. We would certainly hire him/them again - if he's not too booked up, that isc! Highly recommended. Christopher Sykes

Carpentry- 13 Aug 2026
Alex did what I asked and did a great job installing the awning. He also installed a metal shed and put up a beam to cover part of a wall. Overall, the work was good, although a few small details were missed in the shed, which seemed to be due to a lack of attention to detail. I found the price a little expensive, but overall I’m happy

Extensions- 1 Jun 2020
We choose Surrey Build & Maintain because we felt like Dan and the team really listened to our vision for the extension and shared the desire to produce something that would be an amazing improvement to our house. As with any build, there were many hurdles to overcome. Dan and the team were always there on hand to deal with challenges and overcome them in a professional and experienced fashion. We really felt that Dan was on our side and was able to find numerous ways to improve the project as well as saving money by assisting to redesign the structural plans as they were unnecessarily overzealous. The team was punctual and hard-working, often working on weekends to increase the rate of construction. We stayed at the house during the build and Dan made every effort to make the impact on us as minimal as possible, laying dust sheets, cleaning up each day and keeping a temporary kitchen available to us during the project. We took advice on key features like doors and windows from Dan during the build and absolutely loved his design input. The end result is fantastic and we barely use any other room in the house! Since Dan began the kitchen extension we have also employed Surrey Build to overhaul our bathroom as well. Highly recommended!

Questions to ask local loft conversion companies in Hayes

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 Hayes?

A local loft conversion company in Hayes 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 Hayes 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 Hayes 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 Hayes

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 Hayes before agreeing to start the work.

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

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 Hayes 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 Hayes loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
