About our gutter sealing in Cold Ash
Gaps along uPVC fascias and soffits look untidy and can let in water and draughts. We seal them in a colour to suit where possible. Common call-outs are for streaks down the brickwork from a leaking joint and damp on an inside wall under a dripping gutter, across gutter end caps, garage door frames and soffit joints.
Outside joints can only be sealed when they’re dry, so work in Cold Ash is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
There’s a 12-month guarantee on every job, large or small.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Keep an eye out for wet patches below a joint
- Clear leaves and moss from the gutters
- Check fascia and soffit joints for gaps
- Don’t leave a sagging gutter
Clear the gutters once or twice a year 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 and the wall below.
How it works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It generally takes an hour or two for a few joints, longer for a full run. In a small place like Cold Ash, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree which joints need sealing.
- We clean out each joint.
- The joints are dried.
- The sealant is applied and finished.
- The joints are checked once sealed.
Before we arrive
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children

What gutter sealing looks like in Cold Ash
Historic houses like Shaw House (about 2.4 miles west) are a reminder that the area around Cold Ash has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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 site and facilities teams at buildings such as Cold Ash St Mark's C.E. School, larger buildings have long runs of movement joint that eventually need resealing. For landlords with property near Thatcham station, leaking gutter joints on a rental are best caught before they stain the walls.

Common problems we fix in Cold Ash
A sealant applied to a damp or dirty joint won’t bond. Rushed repairs often do not last long.
These are the problems we are asked about most:
- Failed sealant on a garage door frame
- Water dripping where gutter sections meet
- Stop ends leaking at the end of a run
- Damp on an inside wall under a dripping gutter
If you live in an older home near St. Mark's Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Why it’s worth doing now in Cold Ash
New gutters cost far more than a few resealed joints. Where the gutter is in good order and only a joint leaks a reseal is all it needs. If it’s broken or sagging, a gutter installer needs to look. Around Cold Ash, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the amount of work, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.
