Loft Conversion Company in Windlesham
Hi there just a bit about me. Well I’m a time served Carpenter / Joiner by trade and have worked my way up to now owning and running my own company’s for the past 25 years. I have employed up to 20 employees at any one time and build projects from £20k up to £12m for individual clients. So i know how to run a construction company and how to get the job done, but more importantly i believe i understand the stress and pressure all clients can endure if there build is not built within budget and within an honest time line. Everything we do is insured to the highest standards and our workmanship is second to none. I have decided to now move away from the large build sector and back to the smaller more personal builds as this is where i get the most satisfaction and believe I can offer the best service to the client, a happy client is a happy builder. Our work area is anything to do within the construction of your home, even down to the design and getting engineering across the line. Best regards Rod Moran

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.

Carpentry- 2 Feb 2022
I used Crown Carpentry for the first time and found Nick to be very good at his work. He knew exactly what needed doing with the three internal doors we had problems with. We thought two of them would need replacing but Nick was able to fix them quickly and securely with no need for replacement which we were very pleased with! His work was tidy and he thoroughly cleaned up at the end of the job. It took as long as Nick had estimated, he charged accordingly and at the price quoted. We were very pleased with Crown Carpentry and will be using them again if needed. I would highly recommend them to anyone.

Questions to ask local loft conversion companies in Windlesham

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 Windlesham?

A local loft conversion company in Windlesham 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 Windlesham 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 Windlesham 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 Windlesham

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 Windlesham before agreeing to start the work.

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

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