Bal built an extension for us. He was an absolute dream to work with, we are really thrilled. He came in at a very good price. The team were tidy, clean, very professional.

Bathroom Fitting- 25 Feb 2022
This was the best experience I have ever had with a team of builders. Aldo and Leo were polite, organised and their workmanship is of a very high standard. They replaced the bathroom in our rental flat, and it looks really smart. They also refurbished the kitchen, replacing flooring and decorated the whole flat. We have just shown it to an estate agent as we are planning to sell it and they were very impressed. Aldo was very helpful in making suggestions of small changes that would save us money and delivered the project on time and right on budget. Would recommend them and will certainly use them again.

Extensions- 1 Jul 2021
Great job done by Naim and his team. He expressed interest in the job as soon as I posted. If it hadn't been for some wet weather the job would have been completed much sooner in the timescale he quoted. There was one small issue some time after the job was completed. I only called Naim once and he arranged a day to come fix it. We're very pleased with the finish, we would give future work to him and also recommend him to friends & family.

What to ask a Waltham Cross extension builder before hiring?

Before hiring an extension builder in Waltham Cross or extension building company in Waltham Cross, 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 Waltham Cross?

An extension builder in Waltham Cross 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 Waltham Cross 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 Waltham Cross?

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 Waltham Cross 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 Waltham Cross 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.
