Gutter sealing in The Valley
For gutter sealant to hold, the joint has to be clean and dry. So the old sealant and grime come out first and the joint is dried before the new sealant goes in. We’re often asked to deal with dripping gutter ends and earlier gutter repairs that have peeled off, on roofline trims, uPVC fascias and soffit joints.
External sealant needs dry, clean surfaces, so work around The Valley is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
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.
Honest limits
We will not take on work that will not last, so here’s what sealant can’t put right:
- Problems with the roof covering
- Boards that have decayed or split
- Water backing up from a blocked pipe

How we quote for gutter sealing
We don’t publish a price list, because jobs vary so much. The quote depends on:
- The size of the job
- The type of sealant required
- Whether old sealant or filler has to be cut out
- When we can work, for business premises
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

Will you come out to The Valley?

What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Signs you need gutter sealing in The Valley
Overflowing gutters can look like leaking joints. If the downpipe is blocked, water has nowhere to go, which is why we look before we seal.
These are the problems we are asked about most:
- Damp patches inside below a leaking gutter
- Fascia boards with gaps between them
- Old sealant on roofline trims that has split
- Garage door frames letting rain in
Rented homes near Charing station change hands often, and a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

How the job changes by surface
Garage door frames
Garage door frames let rain in when their sealant fails. It’s removed and renewed.
Roofline trims
Trims along the roofline are often finished with sealant. Split sealant lets water in.
Walls and rooflines in The Valley
Historic houses like Belmont House and Gardens (about 2.1 miles north-east) are a reminder that the area around The Valley 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. 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 Church of St Lawrence, an extension built onto an older house moves differently, and the joint between them takes the strain.
