A great experience. Work was completed quickly and to a good standard with an unexpected extra (sorting out the electrics for a light in the crawl space). Most tidy builders I have ever employed. Quick responses and good communication. I'd happily use Prime Contractors again

We have gutted and re-built our whole house and Ronnie has been on the journey with us for 2 years! Ronnie has fitted our amazing kitchen and bathroom which gets a lot of admirers! He has given us lots of options and ideas as well as doing the job as we wanted and how we envisaged our house to look. Ronnie works really hard and is always honest about the jobs and the timescales he can meet. I can feel 100% confident every time I recommend him.

Extensions- 24 May 2024
We asked BLG to complete a different job to the one we advertised as weren't ready to start it. Instead they completed a 2 bedroom flat renovation, including ripping out and installation of kitchen, removing plasterboard walls, making good, painting and decorating and recarpeting/tiling. Their work and professionalism was great but even better was their attitude. They were always quick to find good solutions to problems, were extremely accomodating, informative, hard working and prices were very reasonable - at no point did I feel I was being ripped off or being treated like a mug, which after completing multiple renovations in the past am well aware of. I wouldn't hesitate to recommend them.

Latest review:
Victor (Vica) laid some engineered oak wood flooring for us in a house that we bought at the end of 2013. The house needed lots of work doing and the new flooring was just one of the many jobs undertaken by Victor and carried out to a very high standard for us. He always paid attention to detail, ensured that the flooring was level and that the new skirting board fitted flush to the floorboards. He was also always able to provide a solution to any problems encountered during the renovation works. I would have no hesitation in recommending Victor as he takes the same pride in his work for others as if he was carrying out work in his own home.

Conversions - General- 11 Oct 2022
We've been seriously impressed with Pawel and his team. They opened up our rear dining room/kitchen wall using an RSJ, following our engineer's drawings perfectly. They also did a few bits of plumbing and bricked up one of the windows at the rear, which is where the new kitchen will be fitted. They were incredibly tidy and really pleasant and courteous to be around, which my wife was so grateful for given we live in a busy family house (most builders are not like this...), I can't thank them enough! We will definitely be using them again in the not-so-distant future!

What to ask a West Norwood extension builder before hiring?

Before hiring an extension builder in West Norwood or extension building company in West Norwood, 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 West Norwood?

An extension builder in West Norwood 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 West Norwood 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 West Norwood?

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 West Norwood 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 West Norwood 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.

If you still have questions about the professional you are looking to hire, we have a full detailed guide on hiring the right builder here.
