Trusted gutter sealing in Walliswood

When to call us in Walliswood

When a gutter sags, its joints open. Sealing won’t hold if the gutter keeps dropping so the brackets need attention first.

Keep an eye out for these signs:

  • Garage door frames letting rain in
  • Dripping gutter ends
  • Water dripping where gutter sections meet
  • Damp patches inside below a leaking gutter

Rented homes near Ockley station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls.

About our gutter sealing in Walliswood

Why it’s worth doing now in Walliswood

Replacing fascias because of open joints is generally unnecessary. A neat seal closes the gaps as long as the boards are in good condition. Around Walliswood, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

What gutter sealing looks like in Walliswood

Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

If you live in an older home near Church of St John the Baptist, an extension built onto an older house moves differently, and the joint between them takes the strain.

Landlords, agents and businesses in Walliswood

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.

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.

What we cannot put right

New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:

  • Roof leaks, slipped tiles or failed flashing (a roofer’s job)
  • Boards that have decayed or split
  • Cracked, split or warped gutter sections

If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.

What we do, step by step

We bring everything the job needs with us. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take an hour or two for a few joints, longer for a full run. Somewhere like Walliswood needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. First, we find the drip and check the gutter isn’t cracked or sagging.
  2. We clean out the joint and take out the old sealant.
  3. The joint is dried, because sealant will not bond to a wet surface.
  4. An exterior or gutter sealant is applied to the joint.
  5. The run is checked and any debris near the joints is cleared.

Getting ready for the visit

  • Mention any leaks or damp you’ve noticed
  • For indoor joints, keep the area dry beforehand if you can
  • On commercial sites, let us know about site rules

Related advice

What the job involves on each surface

Soffit joints

Soffits sit under the eaves, where joints can open up. They’re sealed to tidy the line.

uPVC fascias

Open fascia joints look untidy and can let water in. A neat bead closes them up.

Can I do it myself?

If you’ve already had a go yourself, that is fine. We cut it out and start again.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
