An annual boiler service in Paisley keeps small faults small
Boilers tend to fail at the worst possible moment, usually the first cold week of the year. A yearly boiler service in Paisley from CDM catches wear and developing faults before they become a breakdown, and it matters for your paperwork too, because most manufacturer warranties require an annual service to stay valid. Our Gas Safe registered engineers service and repair all major brands, so it makes no difference whose name is on the casing.
When something does go wrong, the same engineers handle the repair. Pressure that keeps dropping, radiators that stay cold, leaks, odd noises, an error code you’ve Googled three times: we find the actual fault and fix it rather than swapping parts and hoping. If you’ve lost heating or hot water altogether, emergency call-outs are available during working hours, Monday to Friday, 8am to 5pm.
Landlords use us to keep the boilers in their rental properties running and their tenants happy, and our commercial plumbing side looks after local businesses as well. CDM is a family-run firm based on Glasgow’s South Side, roughly half an hour from Paisley, with one in-house team and no subcontractors. On Google we hold 5.0 out of 5 from 37 reviews, a score that’s far harder to keep than it is to get.

What’s covered in a service or repair
A proper service is more than a glance and a sticker on the casing. The engineer inspects the boiler inside and out, checks it’s burning correctly, tests the safety devices and controls, and makes sure the pressure and flue are doing what they should. If anything is on its way out, you’ll hear about it then, not in January.
For repairs, the priority is an accurate diagnosis. Once we know what’s wrong you get a fixed written quote for the fix, free and with no obligation, so the cost is agreed before any work starts. And if a boiler is genuinely past saving, we’ll say so honestly instead of charging you to keep patching it.

Boiler service and repair questions
How often should a boiler be serviced?
Once a year. As well as catching faults early, an annual service is a condition of most manufacturer warranties, so skipping it can prove expensive if the boiler fails later on.
Can you repair my make of boiler?
Almost certainly. We service and repair all major brands and see the common faults week in, week out. If parts for a very old model genuinely can’t be sourced, we’ll tell you straight.
I have no heating or hot water. How quickly can you come out?
Phone us on 0141 471 3876 rather than using the form. Emergency call-outs run Monday to Friday between 8am and 5pm, and no-heat jobs are treated as a priority.
Do you service boilers in rental properties?
Yes. We work with landlords across Paisley, Glasgow and Renfrewshire, whether it’s a single flat or several properties, and our commercial plumbing service covers business premises too.
Is it worth repairing an older boiler?
Sometimes, and when a repair will genuinely sort it, that’s what we’ll recommend. When a boiler is at the end of its life we’ll be honest about that too, and a new one from us comes with a minimum 5-year warranty.
