Why do builders get a bad name? The truth is that for every bad story you hear there are hundreds of happy customers. So how do you get the best out of your builder? Improving your home doesn't have to result in contractor chaos says the Federation of Master Builders, the UK’s largest building trade organisation. If you are about to start a major home improvement project, following a few simple guidelines to ensure that you get the best from your builder.

Check them out

Do your research. A building firm could be in your home for several weeks, so it is important that you trust them. Get references, which a good professional will be happy to provide, and check them out. If the builder claims to be a member of a trade association such as the FMB, check what that membership means and find out if they really are members. Scrutinise their credentials before going ahead. Don’t just rely on Yellow Pages, search for a vetted local builder at the FMB’s website

Get a quote

You need several detailed written quotes and not just "It'll cost around £10,000". A good builder would prefer this anyway; it gives them time to really think about the job and what it will entail.

Eager legals

Be aware of the legal requirements you must fulfill when having major improvements done. This is not up to the builder, unless you specifically ask him to do it. The work may require Building Regulations approval as well as planning permission, which can be a lengthy and complicated process – your local council will advise you.

Draw up a contract

As 'project manager' you need to ensure that you know what you want and how you are going to get there. For example, what type of shower or boiler do you want? The cost of the product and installation may vary a great deal depending on the system chosen. A contract is a 100% necessity on every job to prevent misunderstandings, Draw up a written contract, with an agreed timetable that both you and the builder are happy with. The FMB has standard contracts for use by anyone using its recommended builders in “Crystal Mark approved” plain English.

Think about insurance

Extending your home may cost tens of thousands of pounds, so it’s worth protecting your investment. The MasterBond warranty provides cover against faulty workmanship or materials for up to two years and against structural defects for 10 years. Should you move during that time, the insurance stays with the property and is passed on to the new owners. Find out more in the FMB’s “Essential Guide to Improving Your Home”.

Keep talking

Help your builder to understand the look you are going for by showing them magazine pictures of similar projects. Make sure you fully understand every step of the building process and don’t let jargon put you off. A professional builder should explain things clearly to ensure that there are no nasty surprises! If you’re unhappy about the work, talk to your builder immediately. Most things can be amended before they are finished.
