Carpentry- 21 Mar 2022
I have hired Edmond to do a number of projects around our house related to replacing doors, all with odd/custom sizing. Edmond was able to assist in sourcing the doors at the best prices, as well as prepping and hanging the doors once they arrived, along with fitting hinges and knobs. I'll be sure to hire Edmond again for carpenter work and could recommend him.

Loft Conversion- 1 Apr 2022
What can i say, great guys to work with. Came round and quoted as planned. Good competitive pricing. Completed the job better than planned. Always advised and tried to improve on the plans, really have good attention to detail and take so much pride in their work. Job completed bang on time. Never had a issue whatsoever. Arrived on time, good communication and nothing was to much for them. Will definitely be doing my extension next. New to my builder so they dont have much reviews, but not to worry just have a look at their instagram which they update DAILY. You can literally watch them building.. Thanks lads

Loft Conversion Company in Warlingham
I have run my own practice in Architecture since 2005, I work from home, a family man with three children. I also provide structural drawings and calculations, so a one stop shop on that front. Usually saving customers well over £1,000 typically on project drawings. I supply a detailed design spec on all projects to current building regulations, and where necessary detailed 1 in 5 scale drawings for more complicated elements. I have a number of reliable contractors I use regularly, any one of which I would have work on my own home. initial consultations are free of charge, I am happy to discuss your project and look at the overall scope and scale of the project. From there I will provide a detailed fee proposal for both design, planning submission if required, and a full construction package. As my client, you are under no obligation to instruct me for the construction stage after any planning application is successful, you are free to explore other options, of course. I am based in Warlingham, Surrey, prepared to travel within reason, but not to central London.

I recently had a bathroom and utility room refurbishment and am very pleased with the results. Hanif was fantastic, coming up with solutions to transform our bathroom from a tired room to a modern and stylish space.

Bathroom Fitting- 20 Sep 2017
We hired Luca for a job that involved a variety of work across our entire flat. Being totally new to renovation work and having been stung by other builders, meeting Luca was a breath of fresh air – he was friendly, helpful and honest. Luca did an great job for a very reasonable price. He’s fairly new to contracting bigger jobs, but he’s got a lot of previous experience as a tradesman and his plastering in particular was perfect – we’ve had loads of compliments on the quality of his walls and ceilings. He was always on time, always communicated with us fully, and was a pleasure to have around the flat. He made a real effort to keep disruption as minimal as possible and was very patient with us about stuff needing to be moved from one place to another. It wasn’t the easiest job and there were a couple of problems and extras, but Luca takes a lot of pride in his trade and worked extremely hard to keep us happy. We had a couple of plumbing issues arise but he went well above and beyond to resolve them, coming back for 2 days after the job was due to be finished to make sure that everything was working properly. This is far more than we expected, and we did really trust that Luca wasn’t the sort of person that would leave anything unfinished. We’re so chuffed that we met Luca and with the excellent work he did, and would love to work with him again. Luca is going to go on to big things, so if you get the chance to hire him now, we'd recommend him without hesitation.

Landscaping- 3 Jun 2021
On our first meeting I felt comfortable and was glad of input from Robin. Agreed to a plan and only had to wait a few weeks before work could start. All preparations made to protect my drive before skip arrived. All work carried out in a very professional manner and team were very polite and friendly. Even though weather was against ground works they provided shelter so work could continue. I’ve been very pleased with their approach and can’t fault the outcome. Although met with a couple of delays on garden furniture, (nothing to do with Robin and his team, circumstances outside control)all other aspects of this job have met with my approval. Was apprehensive of having people in but can honestly say there have not been any issues and when the skip was removed within an hour, Robin was back on site to clear and wash down the drive. So looking as good as new. It’s been a pleasure having them on my property and will look at using their services again in the future should the need arise. Nothing too much bother. So my thanks to them all.

Questions to ask local loft conversion companies in Warlingham

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 Warlingham?

A local loft conversion company in Warlingham 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 Warlingham 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 Warlingham 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 Warlingham

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 Warlingham before agreeing to start the work.

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

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