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!

Restoration & Refurbishment- 3 Apr 2016
Vidas and his team did a fantastic job with our property refurb project and I can't recommend him highly enough. He completely stripped out property back to brick and rebuilt if from the ground up. We had some quite particular requirements requiring the removal and creation of new partition walls and Vidas was able to accommodate and direct us in how we could address each requirement. We are very happy with the finish and have had many compliments from other tradesmen on the quality of the work. We did have some minor snagging after the project was complete but Vidas was very accommodating in coming back to rectify these issues. I would highly recommend Vidas and look forward to using him again in any future projects.

Questions to ask local loft conversion companies in Mitcham

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 Mitcham?

A local loft conversion company in Mitcham 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 Mitcham 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 Mitcham 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 Mitcham

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 Mitcham before agreeing to start the work.

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

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