What happens at a home improvement survey?

Before the visit

A little preparation makes the visit quicker and the quote more accurate:

• List everything you might want done, even if you are not sure yet.
• Save photos of styles and colours you like.
• Find any old certificates or guarantees for windows, doors or roofs.
• Make sure everyone who decides on the job can be there.
• Clear access to the windows, doors or roof you want looked at.

What the surveyor checks

Measuring is only part of it. The surveyor also checks what is around each opening, because that affects how the job is done.

• Windows: sizes, the condition of the openings, and which upstairs windows need to work as fire escapes.
• Doors: the frame, the sill and threshold, and the brickwork or render around the opening.
• Conservatory roofs: whether the base and frames can carry the new roof.
• Roofline: the state of the fascias, soffits and gutters, and the timbers behind them.

Showing you the options

Expect to see real samples of colours, glass, handles and finishes. It is much easier to choose in your own home, in your own light, than from a brochure.

Ask what each option changes: the look, the warmth, the security or the price.

What a good written quote includes

Before you agree anything, check the quote covers:

• Each product, with its style, colour, glass and hardware.
• What is being removed and taken away.
• Any making good to plaster, render or brickwork.
• Who deals with building regulations, and the certificate you will get.
• The guarantee: how long it lasts and who gives it.
• Who will fit it: the company's own team or a subcontractor.

Fire escape windows and building regulations

Replacement windows and doors must meet the Building Regulations in England. The Planning Portal says a replacement window that serves as a fire escape should give at least the same escape opening as the one it replaces.

An installer registered with a competent person scheme can self-certify the work and give you a certificate when it is done.
