Extensions- 15 Dec 2021
Valdemar and his team of workers were outstanding. I have never known builders to be so thorough, honest and just generally nice people. They can be trusted and gave honest opinions. They were in tune with the building control requirements and worked very hard always arriving on time and working solidly throughout the day. They may be a bit pricey but you definitely got what you paid for - First class workmen ship.

Bricklaying- 25 Aug 2024
AVOID. Ernie incorrectly installed my drains under my house which has caused awful smells and sewage to leak under my house causing long term damage to my foundations Three professional drainage company’s have put a camera to see a Dropped pipe from new to old house. They have identified a connection that was never appropriate. Unfortunately, Ernie after being given many opportunities does not accept any responsibility. He is not an expert at all trades so be careful. I’ve asked him to help put right by exposing the floor which has Underfloor Heating. This has now cost me tens of £000s. My fault for not using a professional team at the beginning of my project.

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.
