Carpentry- 1 Jul 2019
Giles is a very capable carpenter/builder and in the end I was overall ok with the work done. However, his behaviour and care of property left a lot to be desired. He has no customer service skills and the loudness and nature of conversations were not appropriate in a small cul de sac. Despite being asked many times by myself and even his fellow workman he continued to shout and use inappropriate language. The thing that upset me the most was just the lack of professionalism and respect for property. The work required lots of sawing and cutting of tiles. This was done all over my garden lawn and has virtually ruined it, no work sheets under the work table to stop stuff going over lawn. Paint over floor and grass, cig buts everywhere, dried cement left all over road. To be fair Giles did offer to come back and sort stuff out after I had pointed stuff out to him but to be honest I don’t want him back here. He could not sort lawn anyway and I am having to get gardener to sort. He has left bags of sand at front of property which he promised to collect - they have been here for days now. There are other issues which I will speak to My builder directly about. It’s a shame actually because I can see that Giles is actually a pretty amazing carpenter and builder. If he can sort out the other issues I reckon that he will become a top rated.

Daniel quoted comprehensively and clearly for both jobs that I needed, building an extension and a raised patio at the end of the garden. He worked extremely hard and diligently every day. Also he would summarise what he would do next and we discussed any changes etc and which tiles or render I preferred. I am very happy with both the patio and extension and Daniel finished everything off to an excellent standard and went above and beyond the quote. I would not hesitate to use him again and recommend him highly.

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.
