Chasing cost

Pricing is calculated per running metre and changes with the wall material. Plasterboard is quick and quiet to cut. Brick is straightforward standard work. Concrete takes more time, makes more noise and costs extra. The width and depth depend on how many cables need to fit inside. You can see the current rates in the table below.

How the work is done

- Marking out: they mark the chase route — only vertical or horizontal, keeping distance from corners, the ceiling and the floor.
- Wall scan: they check with a detector for existing wires and pipes so they don’t hit anything.
- Chasing: they cut the wall with a wall chaser or an angle grinder with a diamond disc, then open the channel with an SDS drill.
- Cleaning: they remove dust and loose debris from the groove.
- Cable laying: they install the cable in conduit or directly, depending on the requirements.
- Filling: they fill the chase with gypsum filler. Final surface finishing is a separate job.
Chasing rules

- Chases have to run only vertically and horizontally: diagonal grooves are not allowed.
- In load-bearing walls of panel buildings, horizontal chases are forbidden — vertical only.
- Chase depth must stay within 25 mm in a standard wall.
- The minimum distance from gas pipes is 40 cm.
- Several cables may go in one chase, but the total cross-section must not be more than 40% of the channel area.
Warning: cutting into load-bearing structures without permission can weaken the building. If you are not sure, speak to a professional before you begin.
What to prepare

- Plan the route: where the cable starts and where it needs to end.
- Cover furniture and appliances with sheeting: there will be plenty of dust.
- Make sure there is power available for the tools.
- Let the neighbours know about the noise: chasing carries through walls.
- If you want filling and painting as well, say so beforehand.
Wall chasing for wiring in practice: a Warsaw case

A client in Wola was redoing his kitchen and wanted three sockets moved lower, under the worktop. The old ones were at eye level: inconvenient and not nice to look at. Tradespeople cut vertical chases down from the junction box, ran fresh cables and installed the sockets at the proper height. Tradespeople also filled the old openings. The whole job took around three hours for three points, including chasing in brick.
Check the wall with a detector before you drill. How to use one is explained in our wire and moisture detector guide.
Frequently asked questions
Can I chase a load-bearing wall?
Vertically: in most cases yes, as long as the depth does not go beyond 25 mm. Horizontal chases in panel load-bearing walls are not allowed.
How noisy and dusty is it?
Noisy — about like an SDS drill. Dusty: very much so, especially in concrete. Tradespeople use a vacuum while cutting, but there is no way to avoid dust completely.
Who fills the chase after cable laying?
The technician fills it with rough plaster. Final skim and painting are a separate service or can be done DIY.
Can chasing be avoided?
Yes: the cable can be run in surface-mounted trunking. It looks less tidy but it is quick and doesn’t create dust.
How many metres of chase can be done in a day?
In brick — up to 15–20 metres. In concrete: 8–12 metres. It depends on the depth and on how many turns there are.
