Loft Conversion- 28 Dec 2023
Aviraj construction was hired by us to do a loft conversion (to include bedroom & bathroom) and also to refurbish the rest of house plastering, kitchen installation, bathroom installation, electrics, central heating/boiler and plumbing. Firstly I was impressed by how punctual they were and turned up at the agreed time at the first meeting to price the project. This was unlike other builders who either “forgot” or turned up late. The work was completed to a good standard and at no stage did Aviraj construction try and charge more than what was contractually agreed. Furthermore they were happy to fix any issues identified during the project. They were hard working, reliable and got on with the work without requiring supervision. I’ll definitely use them again on our next project! Thanks Guys appreciate all your hard work in getting the project completed.

Carpentry- 14 May 2026
Replaced a rotten external single door. The existing door frame was reused, as per request. This frame wasn't perfectly square which Alex had to compensate for. Alex arrived on time and completed the work without any unresolved issues, taking all offcuts and old door away for disposal.

Loft Conversion- 18 Feb 2024
I wanted to express my gratitude for the exceptional work done by Cool Dudes Construction on my loft and bungalow conversion project. Despite an initial estimate of 12 wks, it was completed to a high standard within 15 wks, with only a minimal 3-wk delay due to 3rd parties (window suppliers) and the holiday season. A complex project. Full rebuild of bungalow, which included hip to gable conversion, rear loft dormer, stair, ground floor extension and full ground floor rennovations (1st & 2nd fix). Mandeep and Balwinder tackled a complex design that involved the integration of steel beams and pillars. They coordinated with various suppliers and also helped me to order skylights, windows, and doors, ensuring timely delivery and installation to keep the project on track. Team always showed professionalism, ensuring that they were always punctual, tidy, and respectful. Commitment to completing the project on time was evident, they maintained open communication throughout. One +ve aspect was their willingness to work with a private building control company that i hired, which ensured compliance with regulations. Another +ve aspect of working with them was clear payment milestones in the agreement. Payment was made on completion of milestones, which provided transparency and reassurance throughout the project. Extremely satisfied with the build and would not hesitate to recommend Cool Dudes Construction to others seeking reliable and efficient building services.

Extensions- 29 Apr 2026
Heera, Jagthar and team was my first personal experience with builders. Let me tell you, it was a pleasure to have them do our porch and other renovations in the house. They are so courteous, hard working and provided a great service. Firstly, I had a comprehensively written quote breaking down all of the steps required. Heera then ensured to keep me in the loop of any developments/any changes of plan required, outlining the reasons why and options, making it easy to understand and work together to completion. Their finish was to a high quality and they would always go the extra step to ensure this. I highly recommend AS Builders for any job and will definitely use them again in the future, and would recommend to my friends and family also. If you are considering them, grab a free quote and go from there... That's what I did! Thank you AS Builders for our renovations!

Gavin and Luke built a single storey extension for us. It was quite complex and they had to remove several internal and external walls. They are very nice people to work with, genuine and honest, amenable. They were here for 9 months doing our work and we are thoroughly happy with them. They are very good - I would certainly recommend them.

Questions to ask local loft conversion companies in Teddington

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 Teddington?

A local loft conversion company in Teddington 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 Teddington 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 Teddington 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 Teddington

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 Teddington before agreeing to start the work.

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

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