Very professional and responsible company. Didn’t cause any disruption to our normal daily live through out the whole project.

We used Vector Living as they were recommended to us by a friend. We were looking for a company to do our fairly large extension and loft conversion. We were nervous about finding a reputable builder as we had heard horror stories in the past. However, from the very start Ash was highly professional and explained the whole process step by step and put us at ease. He provided us with various options we hadn’t considered with not only saved a bit of money but also time. We did encounter unforeseen issues but this is where Vector Living made the difference, they always found a workable option for us. The process of construction was also smooth, always on time and finished to a very high level. We are extremely happy with Vector Living and would highly recommend them. If we ever decide to do a build again will be using them.

Gas Work- 7 May 2024
Florin has done a great job to replace my gas system boiler. He worked hard to finish the job in one day, in fact stayed late evening to make sure the job was completed. He registered the boiler, provided the building reg and Lanlord certificate. I will recommend him based on my experience and will use him again in future.

Carpentry- 22 Mar 2018
Ross and his team did a nice job. I was particularly impressed with the carpentry work, a good finish with a lot of attention to detail, the carpenter was very willing to discuss exactly what was required. Some of the masonry work did require additional correction and had to be pointed out to be fixed. But if I had any complaint it was with relation to some slow communications and removal of waste materials upon completion of the job but overall I would certainly recommend.

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!

Loft Conversion- 26 Dec 2019
Working with Dil was a pleasure! From the the outset he was very helpful with calculating overall costs (over and above his costs) for the build to ensure everything had been catered for and was very thorough in checking that my ideas/plans were appropriate for the long term. It was through the initial discussion that some minor adjustments were made and for the better I believe, simple things like where the new Megaflow System should be placed. He was very quick and efficient in identifying where there may be issues upfront and has the right contacts to get things sorted to minimise problems further into the build. I had to get a new mains water pipe installed which to me was a a major job but he got it sorted very quickly through his contacts at a very reasonable cost. His team are very polite and they do a as good a job as possible to minimise impact on your daily living if like us you are living in the property during the process. Essentially a team of 3/4 guys who are capable of doing most things however Dil does call in specialist trade as and when needed to ensure the job gets done in a timely manner, for my build he called in roofers and certified plumbers for the boiler. Only negative is that you have to watch the silicone sealant finishing which is not the tidiest but a minor in the grand scheme of things and if you don’t like something you simply have to say and he will redo within reason. Overall a very happy customer

Questions to ask local loft conversion companies in Sunbury On Thames

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 Sunbury On Thames?

A local loft conversion company in Sunbury On Thames 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 Sunbury On Thames 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 Sunbury On Thames 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 Sunbury On Thames

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 Sunbury On Thames before agreeing to start the work.

Do I need planning permission for a loft conversion in Sunbury On Thames?

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