Trusted gutter sealing in Barking

Gutter sealing in Barking

We seal leaking gutter joints, end caps, fascia and soffit joints, along with roofline trims and garage door frames. It’s all about the joints, not replacing the gutter. If you’re dealing with failed sealant on a garage door frame and cracked sealant along roofline trims, we can put it right, on soffit joints, gutter joints and roofline trims alike.

Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Period houses have different weak points, such as gutter joints, trims and the line where an extension meets the old wall.

You are covered for a year from the day we finish. If anything is not right with it, ring 0345 464 0079 or email us.

How we quote for gutter sealing

There’s no set price list, because no two jobs are the same. The quote depends on:

  • Mould in or behind the old joints
  • How easy the joints are to reach
  • Whether old sealant or filler has to be cut out
  • How many rooms, windows or areas are involved

Doing several joints on one visit is generally more efficient than separate visits. You will get one clear quote for the whole job.

Asking for a quote

Before you ask for a quote, have a think about:

  • Photos by email, if that is easy
  • How many joints, rooms or windows are involved
  • The address or postcode of the job
  • Any previous sealing or DIY work

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.

Questions from Barking

Is Barking in your area for gutter sealing?

Yes. We work across London and the South East, and Barking is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.

Can you help a landlord with a rental near Barking station?

Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.

When is the sealant fully cured?

Different products cure at different speeds, so follow the cure time we give you.

Are you insured?

Yes. We’re fully insured for every job we do.

Which products do you use?

Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.

Are you ARBOMaster approved?

Yes. We are approved under the ARBOMaster scheme.

Can I do it myself?

Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.

Do the sealants smell?

Possibly a little. It fades as the sealant cures, and ventilation helps.

What we do, step by step

You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes an hour or two for a few joints, longer for a full run for a typical job. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Barking. It helps if you can point us to a visitor permit or a bay close to the door.

  1. We start by tracing the leak and checking the gutter itself is sound.
  2. Old sealant and dirt are removed from the joint.
  3. The joint is dried, because sealant won’t 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.

How to prepare

  • Keep pets and children clear of the area while we work
  • Let us know about stairs, lifts or work at height
  • For business premises, tell us about site rules or sign-in

DIY sealant or a professional job?

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

When to call us in Barking

Gutter joints depend on seals that wear out. Sun and cold make the gutter expand and contract, and old seals crack or slip.

Any of these means the joints need attention:

  • Damp patches inside below a leaking gutter
  • Leaking gutter joints and stop ends
  • Wet patches on the wall under a gutter joint
  • Quick sealant fixes on gutters that didn’t last

If you let a flat or house near Barking station, leaking gutter joints on a rental are best caught before they stain the walls.

What your quote should include

  • What guarantee comes with the work
  • Is the old sealant removed completely?
  • Whether they’re fully insured
  • What the cure time is

How to choose a mastic man

Leave it or put it right?

If the problem is a blocked downpipe, sealing will not help. We check the cause first and tell you if something else is needed. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Barking, the repair is bigger than a sealant job.

What you pay reflects the work, not guesswork. That is why we ask about the job first.

What you get with us

  • Approved under the ARBOMaster scheme
  • Anti-fungal sanitary silicone in wet areas
  • Neat joints and a tidy finish
  • Every job guaranteed for a year

Gutter joints

When a joint drips, the gutter is often still sound. Sealing the joint often stops it.

uPVC fascias

We seal fascia joints, not replace the boards. If boards are damaged, we will tell you.

Gutter sealing in Barking: local notes

Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Eastbury Manor House (about 0.1 miles east) nearby, there’s older building stock in the area around Barking as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.

Managing a site like Eastbury Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. In the older streets around St Patrick's Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

Aftercare tips

How long the joints last depends on use and care. We suggest:

  • Watch for drips in a downpour
  • Don’t lean ladders against the gutter itself
  • Keep downpipes clear
  • Clear leaves and moss from the gutters

Keep the gutters clear of leaves and moss so water doesn’t sit on the joints. Water left in a gutter tests every joint.

The sooner a gutter leak is sealed, the less water reaches the wall. If we find a bigger problem, we will tell you.
