Replacement of a conservatory for a larger more eco friendly and useable space to comprise a kitchen, dining and family room. Shea and his excellent team completed the work to a very high standard and I am very happy with the result. In addition he was charming, friendly and efficient as were his colleagues in the trades who completed their various roles in a friendly manner and with an obvious level of expertise and pride in their work. I plan to have Shea and Mountfair Homes back again for my next round of home improvements and cannot speak highly enough of them.

Bricklaying- 14 Jan 2018
I would like to thank you Johnny for the fantastic job you have done, Johnny came out and looked at the job the day after my posting, he managed to patch in my very old pebble dashing after having a window moved and the back door blocked up, he worked full days in this cold damp weather to get the job finished, I also had a brick step put outside of the patio doors and a lovely brick planter built Johnny even suggested putting some capping on top which finished it off very nicely, he even brought me some soil and put it and the plants I had, into the planter for me, cleaned and washed the yard out, so when I got home there was nothing for me to do, I was very impressed he didn't have to do all that, the price was as quoted, I have already asked for a quote for another job that I need done.

Roofing (Flat)- 8 Jun 2022
Never before have I had so much trouble with a tradesman. N&B were a month late to complete the job, were incredibly hard to get a hold of, untrustworthy, and ultimately constructed a roof that fell away from the gutter, meaning rainwater now ponds against the verge they built and flows back towards my property causing damage. Every time it rains I have to brush the water away. After 5 weeks of failing to successfully contact N&B to resolve the issue (not responding to my complaint) I will have to get my money back for the shoddy work by other means. Other roofers that I invited to quote were astonished as to how they got it so wrong, as was I who made a huge mistake in hiring them. Avoid.

What to ask a Northumberland extension builder before hiring?

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

An extension builder in Northumberland 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 Northumberland 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 Northumberland?

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 Northumberland 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 Northumberland 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.
