Extensions- 2 Oct 2024
He did the extension well, brick work is good, rendering on front of house good, terrace and wall with the neighbours good ,toilet under the stairs good, dividing wall in the living room with sliding doors good, kitchen installed good. Fence wall in front of house good brick work wrong bricks but it’s ok. Herringbone parchet wrong with gaps and lifted, rendering on the side of house wrong with marks, the new boiler took 2 months to make it work and the radiators still don’t work. Electrical work bad, after bringing another engineer to check we discovered at the boiler live cut cables that were loose and veri dangerous. Took 4 months to finish job we waited one month for the plumber who either way did a bad job. Laurentiu did not finish the job because of plumbing and rendering, and we ended in bad terms, he left us money to compensate for it. I would recommend him for extensions and any brick work, he needs to improve in pluming, electrical, flooring and rendering.

What to ask a Swiss Cottage extension builder before hiring?

Before hiring an extension builder in Swiss Cottage or extension building company in Swiss Cottage, 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 Swiss Cottage?

An extension builder in Swiss Cottage 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 Swiss Cottage 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 Swiss Cottage?

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 Swiss Cottage 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 Swiss Cottage 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.
