Groundwork & Foundations- 20 Sep 2018
JPD boys came to rescue us when we were almost stuck with our RC foundation on our project, we got a very competitive quote from them and the job was done to a very high standard. Not only did they helped with that, they also gave us a quote for the block work, again this was done without snagging. We will definitely use them over again and recommend them to anyone anytime.

Landscaping- 23 Jan 2025
CNH did a great job on the bridge of our busy church in central Guildford. We had lots of positive feedback from our parishioners and they matched the colour of the resin bonding very well to the aesthetic of the building. The end result was that it looked like it had always been there, apart from the obvious newness of the surfacing.

Repointing- 31 Oct 2019
Daniel Arrived on time for looking over the job and quoting. His attitude was very favorable in that he wanted to do a good job and was customer focused. He listened carefully to what was required, and we looked over everything together. He eagles eye and attention to detail then came to the fore, pointing out some other aspects not been seen beforehand being done respectfully. He simply explained while I have a mix ready to go it's not any more bother to fill in the extra's. We agreed a cost and a convenient time and day for him to return to do the work. He subsequently returned on time and completed the works, efficiently leaving everywhere neat and tidy, as if he's not even been there, except for the obviously repointing. While he was carrying out the works it became obvious to him that a better, more aesthetic finished job could be achieved, which we discussed and reviewed the plan of work. I am so very pleased with the result; it all looks good and all blends well together. Daniel is an amiable, cheerful person, clearly enjoys his work was keen, not only to do a good job but going the extra mile - above and beyond. I would not hesitate to recommend him.

Latest review:
Ionut and his team helped me with the garage conversion at my house. My initial plan was to utilise the garage as an office space. In the initial meeting, Ionut suggested utlising the space to build a guest bedroom with ensuite as well as an office. I was slightly concerned about this as I always thought that the space was too narrow (3.1 meters) to accommodate all this. However, I am glad that I trusted Ionut’s team as the layout and design was better than expected. The extension is now the best built and most spacious rooms in the house. I would highly recommend Ionut and his team.

What to ask a Crawley extension builder before hiring?

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

An extension builder in Crawley 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 Crawley 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 Crawley?

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 Crawley 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 Crawley 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.
