DIY building surveys

We recommend that you get a professional survey carried out on your building every five years. In between, take a proper look at the building yourself using this guide. If you cannot get owners to take your building’s condition seriously, it might also be worth carrying out your own survey and discussing your findings with your neighbours.

Get prepared

You need to communicate what you’ve found to your co-owners, so get set up at the start:

  • get copies of plans and elevations of your building if you have them
  • or take photographs and print them up black and white, so you can write on them
  • download the survey form and check it covers all the features of your building
  • print off extra sheets if you can, so you have enough to cover all the windows

On your plans and photos, number the chimneys, windows, dormers, and anything else you have more than one of, so you can keep track of what you’ve found.

It may be more pleasant to carry out a survey on a dry day, but wet days can reveal overflowing gutters and drips where it should be dry.

Safe access for checking your building
  • get as much height as you can to check the roof – maybe a neighbour across the road will let you look out of their top flat window
    • if you need to look from the road, get someone to help keep an eye open for traffic
  • can you get safe access to your loft? – you might need someone to hold a ladder, and use crawl boards to avoid putting your foot through a ceiling
  • you may be able to access the roof through a hatch
    • don’t go out on the roof unless you are experienced and have a harness and a sound fixing point for the harness
  • grab a torch, binoculars, camera, clipboard, hard hat, and tough boots
