Loft Conversion- 27 Apr 2022
Completely Surpassed Expectations! We had Williams and his team in to do some under eaves storage. We had what we had in mind, which they quoted for, and whilst doing the work, they identified better ways of doing things, implemented them and still stuck to the agreed price. As these guys do this more than me, they are able to use that expereince, educate the client and achieve phenomenal results. Great value for money, now i have a large, light and usable storage space where I had next to none, my only problem is finding the stuff to fill it with. They even installed lighting meaning it works that much better. Get them in for a quote, if for no other reason than just to understand your options. His team are hardworking, friendly and do the work with a great sense of humor, taking pride in what they do. Gracias Williams!

Carpentry- 18 Aug 2025
Dennis gave a good quote, answered any questions I had, was understanding when the door was delivered damaged and had to put the job back a week. He arrived on time, he was clean and tidy in his work and made easy work of fitting our wheelchair access bathroom door (3ft wide). We are very happy with the finished result and will definitely go back to him if we need a carpenter in the future.

Bricklaying- 11 Mar 2023
The builder came to build a single skim brick wall to the side entrance of my house -: around 120 bricks. He agreed to £300 for labour including inserting a door. Upon arrival, of which he came on foot, he had no tools, no bucket, no drill, no ladder. He had to borrow all of my husbands equipment and sent my husband out for extra materials on two occassions. The lintel he asked us to order was the wrong size, we ordered one that was far too big and wasted more money due to him measuring up the job wrong - again a waste of money. Then, we had to drive him to toolstation to buy a brick cutting tool because of this using our own time and fuel. You would assume a brick layer would have tools if they are doing jobs privately - his colleagues excuse was we are just starting up our private buisness. He then started asking for more money and stormed off leaving all the rubbish behind even though we gave him the £300 as agreed prior to the job. The wall itself is okay but again at one point he refused to build up to the top because of a metal screw apparently impossible to remove, so yet again my husband had to assist with the job and removed the screw. Honestly more hassle than it was worth. Also the door was not fitted so now will need to pay someone else to do the job. I do feel bad for them that do not have any equipment but when you pay money for a job you do expect a certain level of service. I wish them good luck in the future and hope they take this advise on board.

Questions to ask local loft conversion companies in Guildford

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 Guildford?

A local loft conversion company in Guildford 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 Guildford 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 Guildford 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 Guildford

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 Guildford before agreeing to start the work.

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

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