Question 1

What services do extension builders offer?

Accepted Answer

Extension builders can offer work such as rear extensions, side extensions, single-storey extensions, two-storey extensions, wraparound extensions, kitchen extensions, extension foundations and groundworks, and extension drainage. Services vary by business, so check the individual profile before making a request.

Question 2

When should I hire an extension builder?

Accepted Answer

An extension builder can help when you want more living space, plans are being prepared, you need a builder after drawings, and structural work is involved. Check individual profiles to make sure the business takes on the type of work you need.

Question 3

What information should I include when asking for a quote?

Accepted Answer

Describe the problem or work you want done, add clear photos where they can be taken safely, give useful measurements or product details where relevant, and include the property location, access and any deadline. Mention previous repairs, reports or known defects if they could affect the job.

Question 4

What should I check before hiring an extension builder?

Accepted Answer

Before hiring, check the business has suitable experience and that the quote or price is clear. For this type of work, ask about similar completed extensions, insurance, building control process, and payment schedule. Also make sure the extension builder covers your area and takes on the type of job you need.

Question 5

Are there qualifications, registrations or insurance I should check?

Accepted Answer

Qualifications depend on the work involved. Building Regulations and sometimes planning permission may apply, and regulated gas or electrical work must be handled by suitably qualified specialists. Ask who is responsible for approvals, certificates and specialist trades.

Question 6

What can affect the cost of extension work?

Accepted Answer

The price can be affected by size, foundations, structural steel, roof type, glazing, and finish level. Ask for a written quote that explains what is included and how extra work would be agreed.

Question 7

How long can extension work take?

Accepted Answer

How long the work takes depends on size, foundations, structural steel, and roof type. A small, straightforward job can be much quicker than a larger or more complex one, so ask when the work can start and how long it is expected to take once the scope is clear.

Question 8

What should I do before the work starts?

Accepted Answer

Before the work starts, have drawings and approvals available before pricing where possible, agree access for deliveries, skips, plant and material storage, and plan how the household will use the property while parts of it are opened up or without services. Follow any job-specific instructions the business gives you before arrival.

Question 9

When might another trade or specialist also be needed?

Accepted Answer

Depending on the job, you may also need builders, bricklayers, groundworkers, roofers, and electricians. Ask the business you contact what it will handle itself and whether another trade is needed.
