Gutter sealing in Waterloo, done properly
For gutter sealant to hold, the joint has to be clean and dry. So the old sealant and grime come out first, then dry the joint before sealing. If you’re dealing with dripping gutter ends and quick sealant fixes on gutters that didn’t last, we can put it right.
Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Older terraces have their own weak points: gutter joints, roofline trims and the joint where an extension meets the original wall, and both kinds of building are found across London.
Our work is backed for twelve months.

Common questions in Waterloo
I let a flat near London Waterloo station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Is Waterloo in your area for gutter sealing?
Yes, Waterloo is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Can you match the sealant colour?
We help you choose a colour that suits. The choice depends on the product the joint needs.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or email us.
Where is Mr Mastic based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
What the job involves on each surface
Gutter joints
Gutter joints move and sit in water. A gutter sealant made for the job holds best.
Garage door frames
Frame-to-brick joints face the weather. We use a sealant made for outdoor joints.
Gutter sealing in Waterloo: local notes
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Benjamin Franklin House (about 0.7 miles north-west) nearby, there’s older building stock in the area around Waterloo as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Schools such as Oasis Academy Johanna are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. If you let a flat or house near London Waterloo station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. Waterloo is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

How the visit works

Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Waterloo. It helps if you can point us to a visitor permit or a bay close to the door.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Glance at the soffit joints now and then
- Sort out a dripping joint early
- Make sure downpipes aren’t blocked
- Keep ladders off the guttering
Check the joints after heavy rain now and then. It’s the easiest time to see a leak.
The sooner a gutter leak is sealed, the less water reaches the wall. If we find a bigger problem, we’ll tell you.
Why act early in Waterloo
If the problem is a blocked downpipe, sealing will not help. We check the cause first and point you to the right trade if needed. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Waterloo, the repair is bigger than a sealant job.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
When something else is needed
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Brackets that have snapped or loosened
- Leaks from the roof rather than a joint
- Fascias that need replacing
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.
