Gutter sealing for homes and businesses in South Merstham
A drip at a gutter joint is easy to ignore, but the water lands on the same spot every time it rains. Resealing it is a small job if the gutter is otherwise in good order. We’re often asked to deal with drips from gutter joints and end caps and garage door frames letting rain in, on gutter end caps, uPVC fascias and garage door frames.
Houses in smaller places like South Merstham can stand more in the open than those in a built-up town, and walls and rooflines facing the weather take the worst of it. That’s where gutter joints and wall joints tend to fail first.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Glance at the soffit joints now and then
- Have sagging gutters refixed early
- Keep ladders off the guttering
- Look at the gutters while it’s raining
Check the joints after heavy rain. It’s the easiest time to see a leak.
Once roofline sealant splits, water can get behind it. Resealing early protects the boards and the wall below.
Your questions about gutter sealing in South Merstham
Can you do gutter sealing in South Merstham?
Yes. We work across London and the South East, and South Merstham is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear quote.
Is South Merstham within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you have insurance?
Yes, we’re fully insured.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
I rent my home. Can I book you?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
What we are called out for in South Merstham
Debris in the gutter keeps water sitting at the joints. Water that can’t drain works its way through a weak joint and leaks out.
Most people get in touch when they notice something like this:
- Cracked sealant along roofline trims
- Fascia boards with gaps between them
- Earlier gutter repairs that have peeled off
- Water running down the wall below the gutter
Schools such as Merstham Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
Before you book anyone
- Is the old sealant removed completely?
- How hidden problems are handled
- Is VAT in the price?
- Whether you can choose the colour
Surface by surface
Gutter end caps
End caps are resealed where they meet the gutter once clean and dry.
Gutter joints
A dripping joint doesn’t always mean a failed gutter. Resealing is usually enough.
What sealant work can’t fix
A few problems are outside what sealant work can do:
- Boards that have decayed or split
- Leaks from the roof rather than a joint
- Water backing up from a blocked pipe
If in doubt, call 0345 464 0079 or email us and we’ll say what we think.
Joints and surfaces we work on

How it works
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take an hour or two for a few joints, longer for a full run. In a smaller place like South Merstham, 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 trace the drip and check the gutter isn’t damaged.
- The old sealant and dirt are cleaned out of the joint.
- The joint is dried before sealing.
- A gutter sealant is applied to the joint.
- The gutter is checked and debris around the joints cleared.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Tell us about any water getting in
- For business premises, tell us about site rules or sign-in
