Landscaping- 20 Jun 2024
From even before the job started I knew I’d made the right choice. The communication was truly 10/10, not too common nowadays. After 2 long days of hard graft in the summer sun the place looks a thousand times better, we’re dead happy and have met two great guys in the process 👍

Bathroom Fitting- 22 Apr 2023
Younger brother Anti was a professional and I would hire again but beware of the elder sibling as his workmanship his poor, here is a list:- 1) the cupboard fitted under the stairs was misaligned and the hinges are loose. Paint job was poorly finished too. 2) cupboard fitted across the boiler was all bent. Anti came and fixed it. 3) varnish across door and skirting boards were done once and therefore have an uneven spread 4) the floorboards did not have enough glue placed in certain areas so it creaks 5) grout in some time are missing 6) really poor sealant work on the bathroom 7) broke my £2000 TV and then hid the evidence. I only found out after placing the furniture back in its place. In contrast Anti did a good job in fitting the radiator. If you can Illicit promises of Anti only completing the job without the older the brother then go for it or else give them a wide berth.

What to ask a Harrow extension builder before hiring?

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

An extension builder in Harrow 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 Harrow 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 Harrow?

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 Harrow 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 Harrow 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.
