Gutter sealing in Blackwater
Open fascia and soffit joints spoil the roofline and can let weather in. They’re sealed in a matching colour where one is available. If you have gaps along fascia and soffit joints and cracked sealant along roofline trims, we can put it right.
In and around Blackwater, older properties sit alongside newer ones, each with its own outside joints. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Outside joints around Blackwater
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around St Barnabas Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. Schools such as Frogmore Infant School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

Looking after it afterwards
So the new joints stay in good condition:
- Get leaks sealed before the wet months
- Make sure downpipes aren’t blocked
- Clear leaves and moss from the gutters
- Keep an eye out for wet patches below a joint
Keep the gutters clear of leaves and moss so water does not sit on the joints. Water left in a gutter tests every joint.
Split sealant on fascias and trims lets water in behind. Resealing early protects the boards.
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Common questions in Blackwater
Is Blackwater in your area for gutter sealing?
Yes. Our work covers London and the South East, and Blackwater is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing.
Do you work for landlords with property near Blackwater station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
Can you match the sealant colour?
We help you choose a colour that suits. The choice depends on the product the joint needs.
Can sealant stop a sagging gutter leaking?
No. A sagging gutter pulls its joints apart, so the brackets need fixing first.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Is the work guaranteed?
Our 12-month guarantee covers every job.
Can you quote for more than one area?
Yes. Just list everything you need.

uPVC fascias
Our work is the joints, not new fascias. Damaged boards need replacing by an installer.
Roofline trims
We seal the trims, not the roof. A roofer deals with the roof itself.
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Why deal with it now?
Leaving a leaking end cap can send water down the wall all winter. Resealing it is a quick job compared with treating damp later. In an older home around Blackwater, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

A visit to Blackwater is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We find where the water is coming from and check the gutter is sound.
- The old sealant and dirt are cleaned out of the joint.
- We dry the joint so the new sealant can bond.
- We seal the joint with a sealant made for gutters.
- The gutter is checked and debris around the joints cleared.
