A guide price for rising damp injection in your Birmingham home, worked out from published UK prices. It covers the injection only; replastering is quoted separately after we have seen the walls.

## How the estimate works

Your estimate starts from published price ranges for this work, scaled to the size you enter (per m), adjusted for the options you pick, plus any extras you tick. It shows a low-to-high range, not a single number, because every job is different.

## What changes the price

- Whether it really is rising damp, or a cheaper fix such as a gutter, pointing or a bridged path
- How many metres of wall need treating
- How easy the walls are to reach (fitted kitchens and built-in units take longer)
- Whether plaster has to come off and be renewed
- The type of wall: solid Victorian brick or a newer cavity wall

## Where the figures come from

A guide price based on published figures, not a quote. We confirm the price in writing after we have seen the walls.

## Frequently asked questions

### Does the price include replastering?

No. The calculator covers the injection only. Plaster that has taken in salts usually needs renewing, and we price that separately once we have seen how far the damage goes.

### Why is the range so wide?

Published prices run from £60 to £200 per metre of wall (Checkatrade damp proofing cost guide, 2026). Access, wall thickness and how much preparation is needed move a job within that range.

### What if it isn't rising damp?

Then you may not need injection at all. Penetrating damp from gutters or pointing, or condensation, is fixed at the source, and we will tell you that before quoting.
