How we handle gutter sealing in Wallington
Water dripping from a gutter joint can stain walls and soak the ground below. Often a reseal is enough if the gutter is not damaged. If you have gaps along fascia and soffit joints and trim joints where the sealant has failed, we can help, whatever the surface.
Outbuildings, garages and conservatories around homes in places like Wallington add more joints to look after. Leaks usually start at a gutter end, a garage door frame or where an extension meets the house.
You’re covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or drop us an email.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Wallington buildings and the weather
Wallington is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on gutter, fascia and roofline joints, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Wykeham House School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as Parish Church of St Peter and St Paul, an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Fareham station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Your questions about gutter sealing in Wallington
Is gutter sealing in a coastal place like Wallington any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Will you come out to Wallington?
Yes, Wallington is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Is it possible to stop a gutter joint dripping with sealant?
Most of the time. A sagging or cracked gutter needs more than sealant and we’ll say so.
Can new sealant go over the old?
No. We remove every bit of old sealant first.
Are you insured?
Yes, we are fully insured.
How much does gutter sealing cost in Wallington?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours, depending on the number of joints and the access. In a smaller place like Wallington, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First we agree which joints need sealing.
- Each joint is cleaned and any old sealant removed.
- We make sure everything is dry.
- We apply exterior or gutter sealant and finish it neatly.
- The joints are checked once sealed.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Tell us about any water getting in
- Mention any tricky access
How to get a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Get leaks sealed before the wet months
- Keep an eye out for wet patches below a joint
- Rest ladders on the wall, not the gutter
- Watch for drips in a downpour
Leave the new sealant to cure as we advise and avoid disturbing it.
The sooner a gutter leak is sealed, the less water reaches the wall. We’ll let you know if the gutter needs more than sealant.
Why act early in Wallington
A bead squeezed onto a wet joint might hold for a while, but it soon lets go. Cleaning out and drying the joint first is what makes it last. In an older home around Wallington, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first.
