Decking- 14 Jun 2022
James Hynes of JCH Home Improvements have just refurbished our decking area. We thought it was a straight forward job, just to renew the decking and a tidy up BUT the original wood was so rotted the whole area had to be renewed. Joists, upright timbers etc We are thrilled with what James has done, so much more work than anticipated but the end result is fantastic. Would thoroughly recommend JCH Home Improvements and we will be using the again.

Landscaping- 13 Jun 2024
Work done: new retaining wall rebuilt about 900cm high. Two new steps leading onto the lawn built, patio re-grouted, existing garden wall, patio and front driveway power-washed. We are very happy and pleased with the work carried out by Matthew Hassall and his team. Our garden retaining wall had to be rebuilt after it had started leaning over due to work previously carried out by another company. The wall is now much stronger due to the depth of the wall at the foundations and reinforcing steel used to strengthen it. This was a highly involved job. Mathew and his team were punctual, polite and kept us informed of what he was doing at every step. We would highly recommend them.

Kitchen Fitting- 8 Oct 2018
Had three quotes to fit new Wrens kitchen,and picked Stanley even though his quote was not the cheapest.He just seemed a nice guy,and he is.The work was carried out quickly and cleanly,arriving about 08.15 finishing about 17.00.A few minor things need to be carried out mainly due to wrens not delivering all trim but have been told will return as soon as it arrives. I would not hesitate to use Stanley again.Will update when complete.

What to ask a Boreham extension builder before hiring?

Before hiring an extension builder in Boreham or extension building company in Boreham, 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 Boreham?

An extension builder in Boreham 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 Boreham 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 Boreham?

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 Boreham 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 Boreham 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.
