What we’re called out for in Harmans Water
Water spilling over a blocked gutter is often mistaken for a leak. A blocked downpipe makes water back up so we check the cause first.
Common reasons people contact us include:
- Internal damp traced to a gutter joint
- Drips from gutter joints and end caps
- Fascia boards with gaps between them
- Old sealant on roofline trims that has split
Rented homes near Martins Heron station change hands often, and a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

About our gutter sealing in Harmans Water
Many dripping gutters are just a failed joint or end cap. We clean out the joint, dry it and reseal it using a gutter sealant. If the gutter is broken or sagging, we will tell you. We are often asked to deal with cracked sealant along roofline trims and wet patches on the wall under a gutter joint, across roofline trims, uPVC fascias and gutter end caps.
Houses in smaller places like Harmans Water can stand more in the open than those in a built-up town, so exposed walls and rooflines take more wind-driven rain. Joints on those sides are normally the first to go.
Big or small, you get the same 12-month guarantee.

Why deal with it now?
New gutters cost far more than a few resealed joints. Where the gutter is in good order and only a joint leaks, resealing is the sensible fix. If it has failed, we will tell you. In an older home around Harmans Water, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Make sure downpipes are not blocked
- Deal with a drip before winter
- Clear leaves and moss from the gutters
- Check the gutters during heavy rain
Give the sealant the cure time we tell you and avoid disturbing it.
If an end cap is dripping, deal with it before winter. A winter of drips can lead to damp patches inside.
How the visit works
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. The job generally takes a few hours, depending on the number of joints and the access, and we tell you how long to leave it before we go. A visit to Harmans Water is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since 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.
- The joint is dried before sealing.
- A gutter sealant is applied to the joint.
- The gutter is checked and debris around the joints cleared.
How to prepare
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks

Harmans Water: your questions answered
Should the sealant in an older Harmans Water home be renewed?
If it hasn’t been replaced for some years, it’s usually worth it. Sealant is a maintenance item: how long it lasts depends on use, cleaning and exposure.
Do you cover smaller places like Harmans Water?
Yes. Harmans Water is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
What should I tell you?
A short description and the location, with pictures by email if possible. If we need more, we’ll ask.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us.
Do you have insurance?
Yes. Mr Mastic is fully insured.
When is the sealant fully cured?
Cure times vary by product. Before we leave, we’ll tell you the cure time.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
Can I choose the sealant colour?
Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before any work starts.

Surface by surface
uPVC fascias
Our work is the joints, not new fascias. Damaged boards need replacing by an installer.
Gutter joints
Joints between gutter lengths are the most common leak point. They’re cleaned out, dried and resealed.
Outside joints around Harmans Water
Bracknell, which Harmans Water is part of, is one of England’s post-war new towns. Homes here were built in phases, many of them in the post-war decades, so whole streets can have gutters, trims and wall joints reaching the end of their life together. 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.
For an older house near a landmark such as St Paul, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you look after a building such as Harmans Water Primary School, its movement joints, gutters and trims need looking after like any other building’s.
