Gutter sealing in Keynor Estate

Gutter and fascia replacement isn’t our trade, and nor is roofing. What sealant does is close joints; it won’t fix a broken bracket, a cracked section or a blocked downpipe. We work on gutter end caps, soffit joints and garage door frames, and the jobs we see most are water dripping where gutter sections meet and old gutter sealant that has let go.

Outside joints can only be sealed when they’re dry, so work in Keynor Estate is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.

Our work is backed for twelve months, in Keynor Estate and everywhere else we cover.

DIY sealant or a professional job?

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

When something else is needed

It helps to know what we can’t do:

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

If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before you book.

Joints and surfaces we work on

  • Roofline trims
  • Soffit joints
  • Gutter joints
  • uPVC fascias
  • Garage door frames
  • Gutter end caps

Common problems we fix in Keynor Estate

End caps get knocked or pushed by water. If the seal fails, water escapes at the end and runs down the wall.

Most people get in touch after spotting one of these:

  • Streaks down the brickwork from a leaking joint
  • Cracked sealant along roofline trims
  • Internal damp traced to a gutter joint
  • Dripping gutter ends

For site and facilities teams at buildings such as Sidlesham Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

10 questions to ask before you book

What affects the cost of gutter sealing

The price is agreed before any work begins. It’s based on:

  • Whether the work is at height
  • The number and length of the joints
  • The old material and how stubborn it is
  • When we can work, for business premises

What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.

Asking for a quote

When you contact us, these details help:

  • Whether it has been sealed before
  • Where the job is, and your postcode
  • Any access issues, like height or stairs
  • Photos by email, if that is easy

We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or email us.

What gutter sealing looks like in Keynor Estate

Keynor Estate is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on gutter, fascia and roofline joints, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

If you let a flat or house near Chichester station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. In the older streets around St Mary Our Lady Sidlesham, an extension built onto an older house moves differently, and the joint between them takes the strain.

Keynor Estate is about 2 miles north of Selsey, in West Sussex. We carry out gutter sealing for homes and businesses in Keynor Estate, as part of our work across West Sussex.

Aftercare tips

A little care helps the new joints last. Our advice:

  • Watch for drips in a downpour
  • Check that water runs out of the downpipes
  • Get a dropping gutter looked at quickly
  • Rest ladders on the wall, not the gutter

If a gutter starts to sag, get the brackets looked at. If it drops, the joints will open.

Split sealant on fascias and trims lets water in behind. Sealing it early keeps the boards behind dry.

How it works

Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It generally takes anything from an hour or two to a few hours. In a small place like Keynor Estate, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First we agree which joints need sealing.
  2. We clean out each joint.
  3. We make sure everything is dry.
  4. The sealant is applied and finished.
  5. We check our work before we leave.

Before we arrive

  • For indoor joints, keep the area dry beforehand if you can
  • Mention any sign-in or site rules at work premises
  • Tell us about any previous sealing or DIY attempts

Advice

Leave it or put it right?

If the problem is a blocked downpipe, sealing will not help. We check the cause first and point you to the right trade if needed. Older cottages and farmhouses around Keynor Estate can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Why us?

  • White, clear, grey or coloured to suit, where the product allows
  • Sealant colour chosen to suit
  • Over 20 years’ experience
  • Full insurance on every job

Your questions about gutter sealing in Keynor Estate

Do you cover smaller places like Keynor Estate?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Does the coastal weather in Keynor Estate affect outside sealant?

Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.

What guarantee comes with the job?

All our work carries a one-year guarantee, and we’re fully insured.

How long before the joint can be used?

It depends on the product. We tell you how long to leave it before we go.

What does gutter sealing cost?

It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or send us an email and let us know what needs doing and where.

How long does gutter sealing take?

It depends on the size of the job, but most jobs take anything from an hour or two to a few hours. We will tell you when we quote.

Is it worth trying it myself?

You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.

What sealant do you use?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
