Plumbing and Heating Guides

Written by the engineers who do the work, for the half hour before you decide whether to phone anyone. Some of these jobs you can do yourself. We will tell you which, and we will tell you where to stop.

Why These Exist

Most of what gets written about plumbing online is written to be found, not to be read. You search for why your boiler keeps losing pressure, you land on nine hundred words that restate the question four different ways, and at the bottom there is a form. You still do not know whether the thing on your wall is about to cost you money.

Mo started this business in 1999 partly because of how the trade was often run, and the same instinct applies here. An engineer who can explain the fault is an engineer who found the fault. Guessing and swapping parts is expensive for the customer and it is how the trade earned the reputation it spent twenty years shaking off. So these guides do the thing a good engineer does at the kitchen table: say what is actually happening, say what it usually turns out to be, and say plainly when it is a ten minute job you should just do yourself.

That last part costs us work and we write it anyway. Topping up the pressure on a combi boiler is genuinely a two minute job with a filling loop and a steady hand. If you can do it, do it. The call worth making is the one where the pressure drops again next week, because that is a leak or a failed expansion vessel and no amount of topping up fixes either.

Everything here is written against Glasgow housing, because that is what we work in every day and because it genuinely changes the answer. A pre-1919 tenement in Dennistoun with a shared back court gully has different drainage problems from a 1990s estate in Newton Mearns, and a top floor flat has different pressure behaviour from a ground floor conversion. Generic advice written for a detached house in the Midlands is not wrong exactly, it is just not about your building.

What You Will Not Find Here

No scare tactics. A boiler locking out on a fault code is not an emergency, it is a Tuesday, and a guide that tells you otherwise is selling something. There are genuine emergencies in this trade and we say so clearly when we are writing about one, which is the only way the word keeps meaning anything.

No prices we cannot stand behind. Where a guide talks about cost it talks about what moves the number, because that is the part that is actually true for your house. A quote comes from someone looking at your system, and ours comes with a clear price before any work starts. That price is what goes on the invoice.

And nothing about gas that we would not say standing in your hallway. If you smell gas, the number is 0800 111 999, the National Gas Emergency Service, and they attend free. That call comes before ours, every time. We pick up once the escape is made safe.

Three Things Worth Doing Before Anything Goes Wrong

None of the guides below will help you at eleven at night if you cannot find the thing you need to turn off. Five minutes on a dry afternoon is worth more than any amount of reading, and it is the same five minutes whichever of these topics eventually applies to you.

Find your stopcock and turn it. In a tenement flat it is usually under the kitchen sink, occasionally in a hall cupboard or under the bath, and in a lot of older closes there is a shared one as well. Turning it off and on again once a year is the point: a stopcock that has not moved since 1994 will often refuse to move at all, or will refuse to seal again afterwards, and finding that out during a burst is a genuinely bad evening. If it is seized, that is a small job now and a flooded flat later.

Write down your boiler make and model. It is on a sticker behind the front panel or inside the flap, and having it to hand turns a vague phone call into a specific one. It tells us whether the part is on the van, whether the fault code you are looking at means what you think it means, and roughly what the appliance is worth spending money on.

And go and look at your drain covers once, in daylight, so you know how many you have and where they sit. That is the piece of information that most often turns a straightforward drainage visit into an hour of hunting under decking and bin stores before any actual work starts.

Who Is Writing This

Mo, who started the business in 1999 as an apprentice with tools and an unreliable van, and the team who work with him: Muhammad and David on gas and heating alongside Mo, all three Gas Safe registered, David on underfloor heating specifically. Paul leads the drain team with Kyle on the high pressure jetting. Matt takes the emergency callouts. No subcontractors on the core trades and no call centre, which is deliberate, because a reputation that lives or dies locally is the only kind worth having.

Twenty five years, ten thousand jobs, over two hundred and fifty five star reviews, five million pounds of public liability cover and a twelve month guarantee on everything we do, parts and labour. Those are the numbers. We would rather give you those than tell you we are the best in the city.

Communication was excellent from my 1st contact with Moe to the completion of the work. This included follow-up messages…

Our radiator pipe was bent and leaking. They answered straight away… Guy was here an hour later and he was wearing ID, very professional, patient and kind. We just got a new carpet in this room and he done an amazing job on getting little to no water on it. Couldn't recommend enough, price was reasonable.

We lost heating just in time for the coldest day of the year with a baby in the house… When I contacted them they were ready to dispatch that night. Fixed by the afternoon. Quoted that morning and no extra charges were added. Honestly cannot thank them enough.

As a small business owner, I needed a drainage company that could respond quickly. The team attended first thing in the morning, cleared the blocked drain and carried out a full CCTV survey. All documentation emailed across promptly. Professional, efficient and great value for money.
