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.

Restoration & Refurbishment- 18 Feb 2020
I cannot recommend Baz enough! If you want a very skillful and honest builder with great ideas and an eye for detail you will find him in Baz. He will be behind the success of your project. A very good listening ear but also someone that will tell you if your idea is not good as he has so much experience with so many projects! I know he is unusually good at his job and superior to so many others because he was one of 8 different builders I had quote for me some even sent by insurers some found from friend's recommendations. Baz was just so much better than all of them. You won't regret trusting him with your project. He is incredibly experienced, skillful and knowledgeable and surprisingly honest! For a builder this is very rare and exceptional ! I am very happy I used him!

Loft Conversion- 10 Nov 2016
Paul and his team were able to complete the work within the 6-8 week timescale. They were efficient, clean and overall very pleasant to work with. This was our first renovation project so I was really nervous given all the horror stories you hear about builders but Paul was superb to work with. He kept us in the loop throughout the build and if there were any issues he made sure they were dealt with them without troubling us too much. The quality of their work is outstanding and we are so pleased with the turnout. We had a few add ons to the job which Paul accommodated and nothing seem too much for him and his team. He is highly recommended and we will be calling him to come back and do further work on our house.

Chris recently stripped and rebuilt two bathrooms in my flat, and I couldn’t be happier with the result. From the start, he took the time to understand my preferences and worked with my requests while providing expert advice on what was (and wasn’t) necessary from both a safety and future-proofing perspective. His extensive experience and knowledge gave me complete confidence to trust him with the entire project. What really stood out was how approachable he was throughout the process. Chris made it easy to ask questions and was open to last-minute tweaks when needed. He handled everything with real professionalism, from tidying up daily to managing disposal of all rubbish, and he kept my flat in excellent condition with proper floor and surface protection. Renovations are never entirely disruption-free, but Chris ensured everything ran smoothly and with minimal inconvenience. On top of that, his pricing was very competitive, especially compared to other tradesmen who seemed to overinflate or play the system. Overall, I can’t recommend Chris highly enough for his skill, honesty, and professionalism.

Kitchen Fitting- 7 Jan 2021
My experience with Leszek was entirely positive and I wholeheartedly recommend him. I had recently moved property (converted victorian flat) and required a new kitchen installed, shelves built, radiators replaced, painting throughout and some changes to electrics. The work was undertaken around October 2020. Leszek completed the work to a very high and professional standard and I am really happy with the end result. He was easy to get on with, good natured and commutative which made the whole process easy and less stressful for my first experience in home improvements. Leszek was always happy to answer all my questions and further explain the fine detail from electrics to kitchen installation. When small problems arose, he always had a couple options ready to discuss and called promptly to keep me up to date. The kitchen installation is perfect which also included tiling a backsplash. Lezek built some lovely selves in the recesses either side of my fireplace which look brilliant and very smart. The painter and his work was really professional and speedy. Snagging was dealt with and two neighbours independently and proactively commented that the work was done with minimal disturbance to them. From quote to completion it was all in all an excellent experience!

Extensions- 11 May 2018
After a rogue builder left me with 18 (eighteen) structural issues. Lez and his crew came in transformed my failed extension into a masterpiece. All aspects of the job was done to the highest quality and utmost care and attention to detail was shown to building control needs. They cleaned up after every day and made sure the house was habitable, as I had to live there. Every aspect of the build, from the carpentry, plastering and tiling was first class and their recommend electrician and plumbers were from the same stock. Total professionals. My only regret is that I did not use this builder the first time. The prices were reasonable and even building control had good word to say about their work. Thanks Lez

Loft Conversion- 11 Jan 2024
We hired Scott and his team to complete a loft conversion and first floor extension at our property. Scott quoted a fair price and kept to this price throughout the project. Scott's immediate team were all very polite, helpful and respectful, not only to us but our neighbours too. The team were happy to fix all the last bits before sign off. The project ran slightly over time but this was mainly due to the difficulty in coordinating with the contractors who did the tiling. Overall we are happy with the end result and we would be happy to recommend Lambarde Construction to other people.

Bathroom Fitting- 20 Jan 2023
We highly recommend Mario & his team. They fitted a new kitchen & bathroom to a really high standard within a short, timeframe. They work hard, are friendly, professional & honest, my neighbour even commented on how considerate they were! Upon first meeting Mario we were impressed by how organised he was. He arrived on time with the description we’d posted on my builder & went through it methodically. We had A LOT of questions! He answered all of them & didn’t rush us. We received a competitive quote within a day as promised. It included everything we discussed & he quickly answered our follow up questions. We wanted an accurate idea of the cost of electrical work & Mario arranged for his electrician to come & inspect/quote before we’d appointed Mario the job. Our kitchen & bathroom is complicated, with lots of difficult angles. Damp, unlevel floor, unlevel windows, a low ceiling were uncovered in the bathroom. Mario did well to identify solutions, giving us expert advice. Pipes were neatly chased into the wall. Underfloor heating & LVT, tiling, grouting & painting all done to a very professional finish. He kept us informed of progress, checked our preferences & was patient when we had supply delays, finding ways to ensure the job finished on time enabling us to move from our temporary accommodation back home in time for Christmas. He promptly fixed some minor issues after the job finished. We highly recommend Mario & would use him again.

Carpentry- 7 Sep 2021
The cladding was due to start yesterday, Monday 6th of September. In the weekend, I was told they would come do a site visit on Monday instead of starting the job. They came on site yesterday morning and nothing was said about any issues. They said they would start the next day, Tuesday. I got a call at the end of the afternoon (around 5 pm) yesterday to be told suddenly that there are many problems; not levelled portions of frame (which can be easily rectified), no toilet on site (which they knew about - they knew also that the public toilet is only 50 m away), access problems which they also knew about ect... Suddenly a multitude of problems arised! They wanted more money. It is very obvious that they found another job somewhere. I would classify this sort of behaviour simply as not honest. Also expensive- I was quoted £4000 to clad a tiny first-floor(38 m2) . The overall cladding would be 75 m2 in total. Disappointing.

We did a lot of research ahead of our loft build, and spoke to customers of the companies we looked at. We were impressed with Toma and her team from the outset, especially in terms of clarity and communication. We sat down with the project team at the start and walked through the week-by-week plan for our build, then a whatsapp group and weekly meets meant we knew exactly what was happening throughout. Our endless questions were responded to swiftly. Additional optional trade-ups (eg top-hung windows, larger bathroom window etc) were discussed and explained with context, sound advice (and clear pricing where nec) but always still optional. Toma's communication with the teams also seemed strong and continuous, with materials always arriving in time and ahead of when needed, no down-days etc - and importantly, the teams all seemed happy and were just lovely people to have around. I realise with hindsight too that the team's care and workmanship really put them a cut above many others in my area and the project remained on schedule. I wouldn't hesitate to recommend ICS for the whole package and in fact we've also chosen to use them again for a kitchen extension.

Questions to ask local loft conversion companies in Bromley

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 Bromley?

A local loft conversion company in Bromley 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 Bromley 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 Bromley 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 Bromley

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 Bromley before agreeing to start the work.

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

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