Extensions- 5 Oct 2022
I am very pleased with the work Josh and his team did in building my rear extension. They were a friendly and hard working bunch and very respectful of my space. Josh did a great job in project managing the work and making sure things were progressing as planned. Any snagging items were dealt with promptly. I would hire them again if required and recommend them to anyone who wanted to have building work done.

Painting & Decorating- 27 Apr 2018
Claudiu and his team did an excellent job renovating our 2 bed flat in Bushey. He did a great job on the laminate flooring in particular. Installed coving, skirting, painted walls/doors/radiators, installed new light fixtures, and assembled furniture. Will definitely work with him again. In fact, I hired him back to do our bathroom next week!

Landscaping- 3 Jun 2021
On our first meeting I felt comfortable and was glad of input from Robin. Agreed to a plan and only had to wait a few weeks before work could start. All preparations made to protect my drive before skip arrived. All work carried out in a very professional manner and team were very polite and friendly. Even though weather was against ground works they provided shelter so work could continue. I’ve been very pleased with their approach and can’t fault the outcome. Although met with a couple of delays on garden furniture, (nothing to do with Robin and his team, circumstances outside control)all other aspects of this job have met with my approval. Was apprehensive of having people in but can honestly say there have not been any issues and when the skip was removed within an hour, Robin was back on site to clear and wash down the drive. So looking as good as new. It’s been a pleasure having them on my property and will look at using their services again in the future should the need arise. Nothing too much bother. So my thanks to them all.

Our driveway spotlight sensor stopped working - replacement spotlights, new stronger cable fitted, replacement driveway wall mount lights, disability ramp made and driveway washed. pretty straight forward. Sam bought the correct lights, extended cable and the sensor with his electrician from B&Q. Removed and replaced removed all the rubbish, respected our property gave the driveway a wash no hassle - left them to do their work and it was done. I would recommend using them they do what you want and how you want it - He does give you his opinion though up to you if you want to take it or not. happy to use them for further jobs

What to ask a Waterloo extension builder before hiring?

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

An extension builder in Waterloo 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 Waterloo 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 Waterloo?

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 Waterloo 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 Waterloo 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.
