Mandeep has been extremely helpful and allowed me to have assurance that the work would be completed of good standard. I would definitely recommend him to others as it can sometimes be difficult to find honest builders. Mandeep has made sure that all the work was completed of a good standard and any outstanding work that I wanted completed was done on the same day or the following day. He is quick to meet deadlines and I have no complaints.

Extensions- 22 May 2021
I was left in a mess by cowboy builders. I found Sukhvindsr Singh from mybuilders and then I had nothing to worry about. He completed the project with utmost responsibility from erecting heavy steals to all the way up to finish. I was amazed with the level of his skills and above all honesty. This was a massive 66sqm single storey extension and he put up structure, brickwork, fibreglass roof , underfloor heating , tiling,electric work . He even went beyond our agreement to do bits and pieces to make sure i donot get stressed out. I have given him another job in same property to do patio 88Sqm with porceline tiling. Feature wall prepared by him stood out . Highly recommended and i will be surprised if he does recieve similar feedback in his future jobs.

Landscaping- 26 Aug 2026
Professional, clean job and prompt to respond and as soon as we agreed on the job they started next day. Comparing them with other candidates they show good level of flexibility and adaptability required by the job. They show modesty, politeness and non of the off-putting pushy behaviour that is have seen before with other tradesmen. Very confident of the quality of their work therefore paying after the job done. I would highly recommend them.

RS Building successfully delivered two full back-to-brick refurbishments and a new-build development for us in Greenwich, including demolition and construction of four new dwellings. Their level of workmanship is exceptional, and their attention to detail is second to none. As experienced property developers, we’ve worked with many contractors—but RS Building stand out for their reliability, quality, and professionalism. We have since recommended them to several colleagues, all of whom have been equally impressed. Our only regret is not finding them sooner. We look forward to working with them again on future projects.

Loft Conversion- 27 Sep 2020
I met Jay for the first time on mybuilder.com; my job, roof extension received a huge interest; Jay was one of the first that came to discuss and he had one of the best quotes; although we discovered in the last second that the structural calculations were different from what actually the structure is, he was not afraid to get involved, and we worked along the engineer all the way through; his attitude and his team attitude was professional from day 1 until the end; the team came every day at the same hour and they were working really hard; in fact after just 1 day, the old roof was off, new structure was on with a rain proof cover; this thing told me from day 1 how professional and hard working they are and confirmed me that he was the right choice; the extension was done in half time just as a confirmation of above; they accommodated all my requests (like fitting air con pipes); the end result was great, or even better than expected; I truly recommend him and would certainly work with him in future projects.

Loft Conversion- 22 Mar 2024
Glad we didn't hire him. After agreeing on a price for loft conversion and back extension, Mr Rattan kept increasing the price by referring to minor things. Like charging extra for plate that goes on steel. First day when he turned up, he demanded that owner should provide tea and snack for his labour every day. Also he was not ready to include the agreed price on the contract (as he was sub contracting the job to someone else). Glad we cancelled him and hired another builder in his place. I have evidence of all communication I had with him, incase anyone wants it. I would avoid him at all cost.

Questions to ask local loft conversion companies in Staines

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 Staines?

A local loft conversion company in Staines 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 Staines 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 Staines 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 Staines

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 Staines before agreeing to start the work.

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

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