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.

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.

Loft Conversion- 23 May 2017
I had my loft stairs done by Singh. I can only say that he had a great attitude , totally professional. Fully able to listen to what I wanted and provide solutions for any potential problems that came up. Very happy with the end result. The work is of great quality , materials used very good. They said the job will be done in 1 week and this was finished on time as promised. We are now looking at doing more work with them as we are doing a full loft conversion. Would recommend 100%!

Restoration & Refurbishment- 8 May 2012
We hired Audrius initially as his quote was very competitive and I felt confident with his knowledge and practical approach to repair our roof, this was to remove all the slate tiles, lay new felt, new batons and replace with as many usable original tiles, this was organised and completed with as little disruption as possible to ourselves and we were highly pleased with the finished roof. We discussed further renovation works we wished Audrius to carry out so work continued with loft conversion, basement conversion, chimney brests removed, new boundary wall, replastered ceilings throughout, his team were polite and always cleared away when they left for the evening and they were always early in the morning. All problems were sorted quickly and the best solutions found always with costs kept to a minimum, we also changed things here and there and Audrius always had excellent ideas which would save costs and keep our budget in check. Audrius and his team are professionals and we have other work for them in the future and will not be using anyone else.

Hard Flooring- 23 Feb 2020
Andrei provides great communication and very professional service. He was very flexible and worked extremely hard to get all the work done in the shortest time possible, but he did not compromise on quality. He worked very efficiently and considering all the work he had to do, he still left the house clean and tidy. The attention to detail was second to none. I’m extremely happy with my new flooring and would definitely recommend.

I had asked Lee to build me a media wall with a shelf behind the TV so the Sky Box could sit behind it, I also had asked for an electric fireplace to be fitted underneath the TV. Lee was so helpful leading up to the work being done and was always very quick to respond to any question I had. The wall looks incredible it’s everything I asked for and more. It’s so neatly done and I’ve had so many compliments on it already. Lee was so professional and everything was completed very efficiently. I am in love with it and would definitely recommend Lee and his team to everyone.

Restoration & Refurbishment- 6 Oct 2025
Rich and the team have done a fantastic job completing my kitchen and hallway renovation. His team guided me the whole process and were great communicators. No problem was too big or small to handle. There were some issues through the job (due to the initial poor design of the kitchen when it was first built) but the team were quick to resolve this professionally. I would not hesitate for a second to recommend Lux Contracts. Next year, I will be booking them for the rest of the flat! I’m happy to be contacted by prospective customers if any further information is needed. Rhys Gallagher

Questions to ask local loft conversion companies in Dartford

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 Dartford?

A local loft conversion company in Dartford 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 Dartford 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 Dartford 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 Dartford

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 Dartford before agreeing to start the work.

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

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