Bathroom Fitting- 26 Jan 2019
Jav and Joe are nice chaps, gave a very reasonable quote and started really quickly (the following day!). We ended up using someone else for the floor tiles after Christmas (we already know them) so these guys took out our old shower enclosure and fittings and fitted new ones including tiling inside the cubicle. There was a damp issue and a leak beforehand- both of which they repaired to a high standard or came up with solutions to so that the job could compete in time for Christmas. They explained all our options well. They went out to get extra materials without an extra charge and worked at a weekend to get it finished in time. Pleased with the finish and I hear metro tiles are particularly difficult to get spot on. I would have liked a more comprehensive quote beforehand but they provide me with this on request and the job finished on budget except for the work around the unexpected damp which was a small extra charge and we were told about this before we went ahead with the extra work. Good all rounders who can do a whole job like this, altho for anything particularly specialist (such as complex patterned or mosaic floor tiles) I chose to use someone who just does tiling and that id already used- although they do work with a specialist themselves for such jobs and his work examples looked high quality so no need to source anyone extra if you want them to manage the whole thing for you. Would use again.

Khin and Senh did an amazing job redoing all the skirting in our home. Their quote was competitive and their workmanship outstanding. They helped us source the materials to our specification for a great price, handling all the delivery details and were happy to pick up any bits and bobs to get the job done. Each day they arrived on time and often worked late to accommodate the fact we had carpets coming in the following week. After each day tools and materials were squared away and they would send updates on progress. The final product was top quality and has nicely finished off our home as part of a large book of renovations. Finally any snags that I did notice they were happy to come back and address, I couldn’t have wished for any more from these guys. All the best !

Latest review:
I received planning permission for a 3m extension, garage conversion and garden office with a toilet/shower and the architect recommended Timall. We of course carried out all our due diligence before selecting Timall as our builder. I received around 8 final quotes from various legal and reputable builders, and gratefully we chose Timall after checking their previous projects. Timall renovated my townhouse, stripped to brick, repartitioned to be more functional for my family, moved bathrooms, new kitchen etc. The council building control said we needed piling for the 3m extension, and Timall were fantastic to change their plans to carry out other internal work whilst a piling specialist was called in, who Timall also liaised with. The garden office, 3m extension and garage conversion all went well. Parminder the director was very hands-on during the project daily, with his builders on-site daily, honest in his advice, and very experienced in his knowledge of the building industry.

Decking- 29 May 2020
Started on time and completed the decking extension & renovation to a high standard. Ensured that small details like cuts around poles etc, were finished properly and not left with gaps. Next time I would confirm that clearing rubbish is part of the quote, but highly recommend Przemek for quality finish.

I recently used PrimeUK Contractors Limited for conversion works at our studios in Camden, and I couldn’t be happier with the results. The project timeline was set at six weeks, and the team delivered right on schedule. Pavlo and his team had a clear understanding of the scope and what needed to be achieved, going above and beyond to make the project a success. The quality and attention to detail in their work were outstanding, and my entire team was thrilled with the final result. Their pricing was competitive and fair, which was another bonus. When we have more work in the pipeline, Pavlo and PrimeUK will definitely be my first call. Highly recommend!

Extensions- 15 Oct 2020
DPS were superb from start to finish. They were hired to build a single storey rear extension in North London including a new kitchen and bathroom fit. I met Ralph on site along with a number of other builders, Ralph was highly knowledgeable and clearly explained what was required with practical solutions. DPS clearly scoped out the timeline and cost for each stage of the build and kept to this. They completed several agreed extras throughout the job. Communication with Ralph and the whole DPS team was first class throughout. I own a number of rental properties and can comfortably say DPS are the best builders I've dealt with, I cannot recommend them highly enough, they will be my first port of call for future work.

Questions to ask local loft conversion companies in Canonbury

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 Canonbury?

A local loft conversion company in Canonbury 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 Canonbury 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 Canonbury 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 Canonbury

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 Canonbury before agreeing to start the work.

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

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