About our gutter sealing in Sunbury-on-Thames
Failed sealant round a garage door frame lets rain blow in. The frame joint is cut out and resealed with an exterior sealant. If you have fascia boards with gaps between them and earlier gutter repairs that have peeled off, we can help, on gutter joints, soffit joints and garage door frames alike.
Sunbury-on-Thames mixes older houses and their gutters with newer estates of brick, render and uPVC trims. All of those joints move, so they need a flexible sealant rather than a rigid filler.
Each job carries a 12-month guarantee, large or small.

Sunbury-on-Thames: your questions answered
Can you help a landlord with a rental near Sunbury station?

Is gutter sealing in Sunbury-on-Thames guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
How long will you be here?
That depends on the amount of work, but most jobs take an hour or two for a few joints, longer for a full run. We’ll tell you when we quote.
Are you fully insured?
Yes. Mr Mastic is fully insured.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses, and we’re fully insured.
How long should I leave it?
Cure times vary by product. Before we leave, we will tell you the cure time.
What about gutters on a second or third storey?
Low-level work is easiest. We’ll confirm the access for higher gutters once we know more.
For landlords and businesses
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
What happens if it’s left?
You do not need to replace a garage door because rain gets in round the frame. Resealing the frame joint is often enough. Around Sunbury-on-Thames, failed sealant lets water into hidden places, such as under the floor, behind a panel or into a wall. Whatever the joint, failed sealant only gets worse.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.
Why us?
- Approved under the ARBOMaster scheme
- Tidy, careful work
- Colour agreed with you before work begins

Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Aftercare tips
Good habits help new joints last longer. Our tips:
- Clear leaves and moss from the gutters
- Glance at the soffit joints now and then
- Have sagging gutters refixed early
- Make sure downpipes aren’t blocked
Look at fascia and trim joints when you are checking the gutters. A small split is quicker to put right.
If an end cap is dripping, deal with it before winter. A winter of drips can lead to damp patches.
