Ken did a brilliant job fitting my new living room door. His workmanship was excellent, and the finish is perfect. He was professional, reliable, and a genuinely down-to-earth, friendly guy to deal with throughout the whole process. His pricing was also very reasonable, offering great value for the quality of work provided. I’m extremely pleased with the result and wouldn’t hesitate to use him again.

Extensions- 5 May 2019
We’re delighted with the work Jamie and Charlie have carried out for us. Although only a single story extension, it was complicated work with several steels and unusual roof angles to negotiate. Their workmanship and pride in taking care of the details shone throughout. We decided to stay living in the property whilst the work was carried out and they made sure we had a fully functioning temporary kitchen, with insulated temporary wall shielding us from the elements and keeping us secure. They were fantastic with the kids and we thoroughly enjoyed having them around. I’ve never known trades to be so tidy, making sure our space was totally liveable throughout the project and going above and beyond to try and keep minimal impact to us. We decided to extend the project and asked them to tidy up our garden with a fantastic new double patio, hand made wooden pergola and raised beds, and a new garden fence - all completed to their usual high standard and great advice on what would look good. We’re delighted with how it’s all turned out. I wouldn’t hesitate to recommend them to others and we’ll certainly be using them for any future building projects. Thanks guys!

Bricklaying- 14 Aug 2019
Whilst i realised the work I required to be carried out may be too small of a job for some builders to consider it was great that Kyman Construction were happy to offer to view the job. Adam was highly professional right from the initial quotation phase through to completion, all work carried out to a high standard and i have no concern in recommending him for similar work.

Latest review:
We required two extensions - to the rear and above the garage at the side. We contacted Darek as he was recommended to us by a work colleague who lives in our area. We found Darek's prices to be competitive and he was very reasonable to work with, being flexible when our plans changed slightly. Having building work undertaken is never a pleasure, in our view However, we're pleased with the completed work and we found that working with Darek was as stress-free as it could have been. We would (and have) recommended him to friends.

What to ask a Slough extension builder before hiring?

Before hiring an extension builder in Slough or extension building company in Slough, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

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

An extension builder in Slough 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 Slough 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 Slough?

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 Slough 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 Slough 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.
