Extensions- 29 Jun 2017
I can't recommend Rob and his team enough. Rob was friendly and knowledgeable from the very start. At the quote stage he picked up issues with the architectural drawings that no one else had, and more importantly gave us viable solutions. We had already chosen him to be our builder, so luckily he came in with a competitive quote! Rob was very god communication wise, and kept in regular contact with us before the job started and throughout. The build started a week after we had a new born baby, and the guys did everything they could to make life easier for us and get the extension finished as quick as possible. They even worked through two bank holidays and came on the weekend when they needed to. The schedule of works was due to take 5-6 weeks but it was completed in 4 and a half. We also added extras to the build such as some work on the patio and changes to the spec. We were always kept up to date with the costs so there were never any surprises. Rob, Phil and Dave were very conscientious and always left the site tidy at the end of the day. All the guys were easy to talk to and were very pleasant and polite. We are very happy with the end result and plan to use Rob again next year for another job.

Extensions- 19 Sep 2018
Antony Acomb is a very nice guy and talks a good talk, but do not use him for anything other than building a small wall, we had an extension built by Antony Acomb (built! I use that term very losely) it should have taken 10 weeks but after 26 weeks and the work still not finished we had to remove him from our home, everything he had done has had to be redone, apart from the brickwork and that's not great, he didn't even channel out the drainage meaning we had to have a damp proof course and soak away done in a NEW extension, all the plastering has to be done again, the roof needs taking down and redoing, he stuffed plastic bags in gaps and covered with concrete, he didn't level the floor and he didn't even cap off the old drain he just covered it with tiles and then concrete, he didn't remove skirtings before laying the floor, the list is endless, I'm not exaggerating, John Fowler, manager of building control York said it was one of the worse builds he has seen in 30 years, his words were it's so dire, Antony is now trading under AA building and renovation Ltd, he took £15500 Of our hard earned money and then got a solicitor to demand another £3000, so far we have had to pay another £17000 to put it right, clearly this job was too big for him, this will be on going and we won't stop until we get our money back, but we need to warn everyone, tiny job, yes but bigger then stay well clear of Antony Acomb from Acomb maintenance and solutions or AA building and Renovations.

We had our porch renovated by Knowles construction a few months ago. We found Kurt and team to be very polite and professional.

After a frustrating time dealing with the council, Oliver at Northern Planning & Design met with me and quickly produced exactly what was needed for the planning application. I wish I had approached him sooner but but had mistakenly thought the job would be too small for anyone to be interested in.

What to ask a Ilkley extension builder before hiring?

What qualifications and experience do you have as an extension builder in Ilkley?

An extension builder in Ilkley should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Ilkley extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Ilkley?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Ilkley extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Ilkley extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
