We have just moved from Australia into a new house. There is a lot that needs doing. The team were great! I asked them to do considerably more than they were expecting to do. I certainly moved the goal posts several times. Nothing was too much trouble! They were very helpful. Thank you for all your hard work.

Extensions- 25 Jun 2020
We had our porch renovated by Knowles construction a few months ago. We found Kurt and team to be very polite and professional. They went the extra mile to match window design to the existing windows. Overall their work was very neatly finished and they didn't leave a mess. I will recommend their service.

Windows & Doors (uPVC & Metal)- 20 Jan 2020
Did a nice job. The workman on the day was very friendly and worked hard and finished to a high standard. My only gripe is that there was a 6 week wait and a rather hefty deposit. However Terry agreed on a smaller deposit which I can't complain about. So all in all a friendly and professional company. I would recommend!

2 story extension front and back. Luke built the shell up for our 2 story extension, was very professional and knowledge, there was a few unforeseeable issues with the build that he came across which he was able to fix very easily, workmanship was extremely neat and pretty much everybody who has seen the work has commented on how neat it has been, our plasterer who came in afterwards has he's taken a lot of care not just inside but also on the finish inside as a lot of builders only care about outside and leave other to sort the inside out but luckily not luke, he also helped out massively when let down by other trades to help catch up and get ready for 1st fix trades, we also added in a lot of extras which weren't originally discussed but the work got carried out as usual to a very high standard at a very reasonable cost. They work very fast only really being held up by weather. I would definitely recommend Lh builders for any building work you need.

What to ask a Lancaster extension builder before hiring?

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

An extension builder in Lancaster 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 Lancaster 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 Lancaster?

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 Lancaster 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 Lancaster 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.
