Extensions- 23 Sep 2023
I hired Jake, Brian and the team to carry out a single story kitchen extention. I had never undertaken such a large job and was somewhat overwhelmed and did not know what to expect. However, I was reassured by Jake and Brian on what to expect and what the works world entail. They took the project on and were in constant communications throughout the build. They organised building control inspections, kitchen fitters, electrical, plumbing, plastering, brick layers, the lot. I just had to sit back and see my dream kitchen come into fruition and boy it did! No job was too small, they made adjustments along the way and kept me informed of any issues and made me aware of anything that required extra work, we agreed to a price and they delivered. I am very happy with the outcome and any issues that came up later were dealt with promptly. I had some frustrations along the way(this wasn't jake's fault) but Jake took on the responsibility and rectified issues that were not his own. Its difficult to find a trustable and reliable builder these days but if you are reading this, please give Jake a shot, you will not be disappointed. I now have the kitchen I envisaged at a reasonable price and I couldn't be more happier. If you want a builder who is trusted, has an eye for detail and is always transparent... do yourself a favour and get in touch with J S Build & Renovate. Jake is a genuine hardworking lad that deserves the recognition!

Roofing (Pitched)- 3 Nov 2021
Isaac did several jobs, a reslate of the extension, house Krender and a new front canopy. Along the way, he uncovered elements of concern effecting the integrity of the house. I was kept updated and Isaac offered efficient solutions, making sure of reasonable pricing throughout. Issac has a team of workers, all of which were pleasant to liaise with, keeping the working site in order, as the jobs progressed. So pleased now, after all the work, to have confidence in how the house has been upgraded and has a bright fresh appearance.

What to ask a Darwen extension builder before hiring?

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

An extension builder in Darwen 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 Darwen 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 Darwen?

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 Darwen 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 Darwen 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.
