    Hi, I'm Craig a self employed Carpenter. I have been in the industry for 13 years. I began my career with a high quality builder in Wokingham where I worked for 5 years earning my NVQ in Site Carpentry. The work there included a mixture of renovation, extension and new build projects aswell as Kitchens and bathrooms. Upon leaving i was presented with an opportunity to move into the commercial side of the industry working in shop fitting carrying out 2nd fix and kitchen installation for Sainsburys both in there stores and in there offices in Holborn and Coventry. During this period I also worked at Guys Hospital installing hardwood decking to the balcony and break out areas in the new cancer wards. I also have a lot of experience in the structural side of Carpentry I.e Truss roofs, hand cut roofs, Joisting and staircases which I gained from working for various builders, my own clients and time spent on new build projects. I am based in Reading and am prepared to travel. I do enjoy hand cutting roofs but am equally at home inside hanging doors and carrying out the 2nd fix side of Carpentry. I believe in carrying out all jobs to the best of my ability, and that good communication beetween myself and my client is a must

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.
