Extensions- 29 Sep 2024
Outstanding!!! If you want professional, honest and hardworking builders - look no further. We can't rate Franklin and McKenna highly enough. The level of communication was high, right from the start they always kept us informed and updated regarding, when they were coming, materials etc. They always turned up when they said they would. We felt they went above and beyond - sourcing high quality materials and other trades, at reasonable and sensible prices. They only purchased enough materials required for the job - hence not wasting our money on materials that were not used. We are so pleased we found them - so much so that, they are coming back to do further building work for us. We have already highly recommended them to others and will continue to do so. We can honestly say that they NEVER Let us down and feel they are excellent value for money.

What to ask a Rainham extension builder before hiring?

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

An extension builder in Rainham 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 Rainham 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 Rainham?

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 Rainham 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 Rainham 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.
