Waste Clearance- 25 Oct 2016
What a fantastic professional company! So glad I chose them. I wanted a concrete slab removed from my garden. Their quote came quickly and the price was reasonable for the work involved, which included removal of all debris. When I phoned to arrange a start date, I was fortunate that some of their workmen were in my area; about to finish another job, and so they were able to fit in mine immediately! The three workers were extremely hard working, polite and efficient. When the job was finished I was contacted to ensure that I was totally satisfied; which I was - I have no hesitation in recommending Spaw Construction. I would definitely use them again.

Windows & Doors (uPVC & Metal)- 3 Jun 2021
Charlie Malyon of Malyon Home Improvements was very professional and cost effective and did an excellent and quite difficult job replacing 10 frosted double glazed panes in wood surrounds. I would most certainly recommend him to others.

Bricklaying- 26 Jun 2017
Chris & Tom arrived early and worked continuously and took trouble to get the right coloured sand to match existing mortar. One or two niggely problems with the lintels which Chris had to travel some miles to obtain from different merchants were overcome without any moans to me (the customer) and without any downtime on their part. I`m very pleased with the job and to have got the job done. The work area was left clean and hopefully Chris will be available to build a brick wall in front of my bungalow when I`m looking to get this done. Excellent and recommended.

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.
