Latest review:
We required two extensions - to the rear and above the garage at the side. We contacted Darek as he was recommended to us by a work colleague who lives in our area. We found Darek's prices to be competitive and he was very reasonable to work with, being flexible when our plans changed slightly. Having building work undertaken is never a pleasure, in our view However, we're pleased with the completed work and we found that working with Darek was as stress-free as it could have been. We would (and have) recommended him to friends.

Matt built our front porch. Matt paid lot of attention to detail and did an excellent job. He didn't tried to cut corners his advice/suggestions were practical and professional. We are very impressed with the quality and professionalism of the work. His work was very clean and tidy and would tidy up any mess before he left at the end of the day. If you're looking for hard working, reliable, clean reasonable and responsive builder look no further.

Landscaping- 12 Jan 2021
Brady and the lads did a fantastic job building me a fully insulated rendered block garden room. I went for Ellis Phillip because both Brady and Andrew are genuinely decent and trustworthy guys. They were tidy from the onset and even covered my whole driveway in a layer of board and plastic sheet before the job started to prevent and damage and mess. Good quality of work and finish. Brady uses the same teams (eg plasterers, electrician, etc) for his jobs and they all work well together and communicate all aspects of the job with each other which helps alot. Nothing was too much trouble - we made numerous last minute changes throughout the job and he was happy to accommodate them. Job finished in a decent time scale. We're extremely pleased with the finished result and would definitely use again and recommend to friends and family.

Groundwork & Foundations- 18 Dec 2020
Had three quotes for a base for a garden shed, Toma was the cheapest by far. We arranged a day for the work to be done, bit apprehensive because I never knew anything about the company. Mr Toma and two others turned up, what lovely people they were, especially Mr Toma, the job was highly professional, everything was tidied up. Would I use them again.........100%. I would highly recommend them.

What to ask a Watford extension builder before hiring?

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

An extension builder in Watford 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 Watford 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 Watford?

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 Watford 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 Watford 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.
