Extensions- 13 Nov 2020
Avoid these traders. They are amateurs and have caused me no end of pain with a small single storey front extension. I sacked them in the end as we just could tale anymore of their slap dash approach.

Restoration & Refurbishment- 27 Mar 2022
Ricky Reid I was looking for a company who could help me with a light refurbishment (kitchen, bathroom and full decoration) of a one bedroom flat in south west London to be ready for rental within 15 days. I posted my ad request on mybuilder.com and a few companies contacted me. Ricky Reid, was the third one I met and eventually the one I chose. Why? R. was straight forward, no gimmicks and did his best to understand what my needs were from day one. Especially when my vision at the start wasn’t that clear. Him and his team delivered within the time frame agreed as well as within the quote given plus a few extras that hadn’t been considered at the start of the project. He was always available for questions or clarifications needed over the phone at any time! A rare quality in itself in the building world. If there was anything that could be improved, this would be clarifying certain jobs that were on the quote (and I mean specifically what they exactly covered) from the start to avoid stingy or unexpected surprises cost wise. However this isn’t Ricky’s fault and I take my full responsibility as I should have done my homework before hand. Overall satisfied with the result and I would certainly contact Ricky and his team for my next future projects and so should you reading this review. Thank you Ricky and all the best in your company venture.

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.

Plastering- 16 Mar 2020
Almed and his team came over to see the two bungalows and gave me a quote and was more reasonable than other quotes I had previously. Almed started the job and stated exactly what he was going to do from the beginning to the end of the job. He is a very professional and knowledgeable person and he and his team did a outstanding plastering job on my two bungalows and I’m very happy with the job and will highly recommend him for future projects.

Bricklaying- 11 Mar 2023
The builder came to build a single skim brick wall to the side entrance of my house -: around 120 bricks. He agreed to £300 for labour including inserting a door. Upon arrival, of which he came on foot, he had no tools, no bucket, no drill, no ladder. He had to borrow all of my husbands equipment and sent my husband out for extra materials on two occassions. The lintel he asked us to order was the wrong size, we ordered one that was far too big and wasted more money due to him measuring up the job wrong - again a waste of money. Then, we had to drive him to toolstation to buy a brick cutting tool because of this using our own time and fuel. You would assume a brick layer would have tools if they are doing jobs privately - his colleagues excuse was we are just starting up our private buisness. He then started asking for more money and stormed off leaving all the rubbish behind even though we gave him the £300 as agreed prior to the job. The wall itself is okay but again at one point he refused to build up to the top because of a metal screw apparently impossible to remove, so yet again my husband had to assist with the job and removed the screw. Honestly more hassle than it was worth. Also the door was not fitted so now will need to pay someone else to do the job. I do feel bad for them that do not have any equipment but when you pay money for a job you do expect a certain level of service. I wish them good luck in the future and hope they take this advise on board.

Conversions - General- 11 Aug 2026
Very professional and proactive from the first contact. He took the time to understand our renovation project properly, offered a lot of useful and practical advice, and prepared a detailed cost plan for us. He even worked over the weekend to revise the proposal and try to accommodate our budget. Although we eventually decided to proceed with another contractor whom we had already been speaking to before making contact, I was extremely impressed by his communication, attitude and professional approach throughout the quotation process. I would be very happy to contact him again for future projects.

Questions to ask local loft conversion companies in Cranleigh

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 Cranleigh?

A local loft conversion company in Cranleigh 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 Cranleigh 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 Cranleigh 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 Cranleigh

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 Cranleigh before agreeing to start the work.

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

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