Gutter sealing near Cottered

What happens on the day

All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes anything from an hour or two to a few hours. In a small place like Cottered, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We look at where the water is coming from and check the gutter isn’t broken or sagging.
  2. We clean out the joint and take out the old sealant.
  3. We make sure the joint is dry before sealing.
  4. Gutter or exterior sealant is applied and finished.
  5. We check the run and clear any debris we find while we are there.

Before we arrive

  • Clear the area around the work
  • Let us know about stairs, lifts or work at height
  • Plan for the work area to be out of bounds to pets and children

How we handle gutter sealing in Cottered

A drip at a gutter joint is easy to ignore, but the water lands on the same spot every time it rains. Resealing it is a small job if the gutter is otherwise in good order. We work on gutter end caps, uPVC fascias and roofline trims, and the jobs we see most are damp patches inside below a leaking gutter and gaps along fascia and soffit joints.

Outside joints can only be sealed when they’re dry, so work in Cottered is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What gutter sealing looks like in Cottered

London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Homes close to Parish Church of St John the Baptist include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

What sealant work can’t fix

Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:

  • Roof leaks, slipped tiles or failed flashing (a roofer’s job)
  • A gutter length that has split
  • Water backing up from a blocked pipe

If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.

Common questions in Cottered

Do you cover smaller places like Cottered?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Can you do gutter sealing in Cottered?

Yes. Our work covers London and the South East, and Cottered is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.

Is it possible to stop a gutter joint dripping with sealant?

In most cases, yes. If the gutter is sagging or cracked, sealing won’t last and we will say so.

How long will you be here?

Most jobs take anything from an hour or two to a few hours, including preparation and clearing up. We’ll confirm how long when we quote.

Is it OK to seal over old sealant?

No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.

Can you quote for more than one area?

Yes. Just list everything you need.

Does someone need to be in?

We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.

Where are you based?

Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.

Keeping the joints in good condition

To keep the joints looking good and working properly:

  • Clean out the gutters once or twice a year
  • Look along the fascias for open joints
  • Check that water runs out of the downpipes
  • Rest ladders on the wall, not the gutter

While checking gutters, glance at the fascia joints too. Splits are easier to seal early.

A leaking stop end is best sealed before the wet months. A winter of drips can lead to damp patches inside.

Why deal with it now?

Sealing over a dirty, wet joint is a quick fix that rarely lasts but it tends to peel off. Proper preparation is the difference. Around Cottered, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Common problems we fix in Cottered

Roofline sealant ages in sun and rain. It hardens, shrinks and splits over time.

If you can see any of these, it’s time to have the joints looked at:

  • Cracked sealant along roofline trims
  • End caps that drip every time it rains
  • Gaps along fascia and soffit joints
  • Earlier gutter repairs that have peeled off

For site and facilities teams at buildings such as Freman College, larger buildings have long runs of movement joint that eventually need resealing.

What to look for in a quote

  • How much experience the applicator has
  • Whether you can choose the colour
  • How hidden problems are handled
  • Whether all the old sealant comes out first

Choosing a sealant specialist

DIY sealant or a professional job?

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Work for landlords, hotels and businesses

Landlords and agents in Cottered can book us as well as householders. Resealing between tenancies keeps a property looking cared for.
