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

Restoration & Refurbishment- 18 Nov 2017
We were initially very impressed with Vilmos's work and communications with him. However, he has not completed the work and has been uncontactable since end Aug 2017. Vilmos identified and fixed a lot of errors made by a previous builder such as leaks in the bathrooms. He carried out works as requested by building control and as far as we can see these works were completed. We were especially happy with our communications with him as we were based overseas. The final step is for Vilmos to meet with the building control and get the building works signed off. However, Vilmos has suddenly become uncontactable via phone and email and has not contacted building control to carry out the final step.

Sean did a full refurbishment on our house. He is the most organised and customer friendly builder I have ever used. From start to finish there was a plan of action and then a great group of qualified tradesman to execute. Like every refurbishment, we asked for changes and he always made us feel like the extras were no problem. I have no hesitation in recommending CG Carpentry. They are now our go to builders and in our next move he will be the first person I call.

Carpentry- 21 Dec 2025
Viktor and Michael are very friendly and professional. They were on time and the price quoted was the price I paid. I hired them to install architraves around 4 internal doors and I am very happy with their work. They made sure I was happy with the work before they left and they took time to clean up after as well. They take real pride in their work as all the joints are perfectly aligned and all the nails are sunk in to the wood so I can apply filler afterwards and paint. Viktor also made a quick trip to Screwfix to ensure he used the strongest adhesive to fix the architraves to tiles in the bathroom. I will hire Viktor and Michael in the future to refurbish my stairs and install wall panelling on the stairs wall. I highly recommend them for their honest and professional work.

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 Merton Park

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 Merton Park?

A local loft conversion company in Merton Park 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 Merton Park 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 Merton Park 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 Merton Park

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 Merton Park before agreeing to start the work.

Do I need planning permission for a loft conversion in Merton Park?

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