Gutter sealing in Monk's Gate

Common problems we fix in Monk's Gate

Water spilling over a blocked gutter is often mistaken for a leak. A blocked downpipe makes water back up, which is why we look before we seal.

Signs it’s time to call us include:

  • Trim joints where the sealant has failed
  • Earlier gutter repairs that have peeled off
  • Streaks down the brickwork from a leaking joint
  • Fascia boards with gaps between them

Letting a property close to Horsham station? Then a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

Questions to ask before booking

  • How the colour is chosen
  • Whether they’re fully insured
  • When the joint can take water or movement
  • How the surfaces are prepared before sealing

About our gutter sealing in Monk's Gate

Across Monk's Gate, we reseal gutter joints, end caps and roofline trims. Low-level work is straightforward and if it’s higher up, let us know and we’ll confirm what access is needed. If you have stop ends leaking at the end of a run and damp patches inside below a leaking gutter, we can put it right, whatever the surface.

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

The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

What happens on the day

Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from an hour or two to a few hours. In a small place like Monk's Gate, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We look at the gutters, fascias and trims and agree the joints to seal.
  2. We clean out each joint.
  3. The joints are dried.
  4. We apply exterior or gutter sealant and finish it neatly.
  5. The joints are checked once sealed.

How to prepare

  • For business premises, tell us about site rules or sign-in
  • Tell us about access, such as stairs, a lift or high-level joints
  • Where the joints are inside, avoid wetting them before we arrive

Surface by surface

uPVC fascias

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

Roofline trims

We seal the trims, not the roof. A roofer deals with the roof itself.

How to look after the new joints

Once the sealant has cured, a few habits help it last:

  • Get leaks sealed before the wet months
  • Keep ladders off the guttering
  • Look along the fascias for open joints
  • Check the gutters during heavy rain

Keep downpipes clear, so water can get away. A blocked pipe backs water up to the joints.

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

DIY sealant or a professional job?

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Common questions in Monk's Gate

Will you come out to Monk's Gate?

Yes. Monk's Gate is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

I let a flat near Horsham station. Can you help?

Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or email us with the details for a clear quote.

Can you reach high gutters?

It depends on the access. Let us know the height and the ground below when you ring 0345 464 0079 or send us an email.

Do the sealants smell?

Some sealants have a smell while they cure. Ventilation helps.

Is gutter cleaning part of the job?

We clear debris near the joints because the joint must be clean. Cleaning the whole run is a separate job.

Is it worth trying it myself?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.

Which products do you use?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

Will sealing fix a sagging gutter?

Not for long. The movement opens the joint again, so the fall and brackets need sorting first.

When something else is needed

Some problems need a builder, plumber or other trade rather than us:

  • Problems with the roof covering
  • Fascias that need replacing
  • Cracked, split or warped gutter sections

Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before you book.

Gutter sealing in Monk's Gate: local notes

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.

Schools such as St Andrew's CofE Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you live in an older home near Church of the Good Shepherd, the joints between older walls, newer extensions and the roofline need a sealant that can move.
