Driveways (Paved & Loose)- 20 Mar 2026
What can we say about Regal Construction Ltd.... Bobby and his team of Louis and Ricky have been exceptional throughout. From the first meeting with Bobby we knew he would do a fantastic job. Flexible and helpful planning a new driveway and patio and full of ideas to help us along the journey. Bobby is without doubt the hardest working tradesman we've encountered after multiple renovation jobs over the last 5 years. Skilled, driven and professional. Arrived early each day and left late despite a long commute home. The guys were all brilliant. Friendly, polite and hard working. Clean workers, tidying away daily and great communication. We plan on having an extension next year and without doubt will be requesting this team do the work. We love our new drive and patio. Thank you guys for all your brilliant work. Can't believe we're the first feedback on mybuilder as there should be 100s. I've seen Bobby's other work in photos to help with ideas and it's all great. A++++

Conservatories- 14 Dec 2022
Kyle has carried out the removal and replacement of our lean-to conservatory. His advice at the initial visit and throughout the work was very helpful and he was prompt in submitting his quotation. Once the order was placed he informed us of the starting date and arrived with all the materials required which ensured that the work progressed quickly and was completed within the given timescale. Kyle was very competent, polite and friendly and cleaned up thoroughly after job was completed. We are very satisfied with the work carried out and from our experience would be more than happy to recommend K. Ransley Installations.

Restoration & Refurbishment- 11 Sep 2022
My partner and I couldn't be more thrilled with the service and standard of workmanship that Matt and his team have achieved on our recent first floor conversion. The quality of the finish is fantastic and I would have no hesitation in recommending him to family and friends. Throughout the whole build communication was brilliant and at no point did Matt or Tony ever assume or make any decisions without consultation or checking in. Problems and solutions were worked through jointly and nothing was every to much trouble especially as the scope of what we originally asked for grew as the build went on. This was driven by us adding items to the original brief. They were really helpful with recommending showrooms and suppliers which made the decision making process streamlined. We were lucky to move out for the build but everyday our home was kept clean and tidy. Finally all snagging has been dealt with promptly and it's lovely to see that the company is also striving for a high standard of finish. Thanks very much for everything.

What to ask a Cowes extension builder before hiring?

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

An extension builder in Cowes 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 Cowes 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 Cowes?

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 Cowes 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 Cowes 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.
