Your questions about external mastic in Brantham

Is Brantham within the area you cover?

Yes, Brantham is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Do you work for landlords with property near Manningtree station?

Yes. We work for landlords and letting agents as well as homeowners. You can phone 0345 464 0079 or email us with the details for a clear quote.

Do you have insurance?

Yes. We are fully insured.

Do the sealants smell?

That depends on the sealant. Some smell for a while, some hardly at all.

Do you guarantee your work?

Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.

Can you work on commercial sites?

Yes. Hotels, offices and other businesses use us and we’re fully insured.

Do you take out the old sealant first?

Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.

Can you seal joints between render and window frames?

Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides with primer where required.

Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. We’re often asked to deal with failed sealant between panels on a façade and failed seals between different materials, across façade panels, render & cladding joints and concrete & block.

In a village or hamlet like Brantham, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.

Every job is covered by a 12-month guarantee.

Why deal with it now?

Sealing over the top of old mastic does not hold for long. The new layer cannot bond properly to old, weathered material, so we always take the old sealant out. Where a wall is exposed, as many are in small places like Brantham, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Rather than a set price list, 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.

What affects the quote in Brantham

There’s no set price list, because no two jobs are the same. What we look at:

  • The product the joint needs
  • Whether old sealant or filler has to be cut out
  • Whether the work is at height
  • Any mould that needs treating

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.

Asking for a quote

There’s no need for technical detail. Just tell us:

  • Any access issues, like height or stairs
  • The address or postcode of the job
  • What’s wrong with the joints now
  • Whether it has been sealed before

Brantham buildings and the weather

Brantham 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. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Historic houses like Castle House (about 3.2 miles west) are a reminder that the area around Brantham has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.

For site and facilities teams at buildings such as Brooklands Primary School, larger buildings have long runs of movement joint that eventually need resealing. Homes close to Church of St Michael and All Angels include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

DIY sealant or a professional job?

Overfilling a joint is a classic DIY mistake. 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: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Do you need external mastic in Brantham?

Some movement joints have been pointed up with mortar by mistake. The joint cannot move, so the wall cracks somewhere else instead.

Signs it’s time to call us include:

  • Joints where the bead has come unstuck
  • Rain getting behind render or cladding at a joint
  • Old sealant gone brittle and cracked
  • Weeds or debris growing in open joints

If you let a flat or house near Manningtree station, outside joints that have cracked can let damp into a rental, so check them between lets.

Questions to ask before you book

  • Who turns up on the day
  • Whether they’re fully insured
  • Whether all the old sealant comes out first
  • What happens if they find a problem under the old sealant

Choosing a sealant specialist

The process

Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from a few hours to several days, depending on the building. In a small place like Brantham, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First, the joints are inspected and the access agreed.
  2. We cut out the old mastic and rake out anything in the joint.
  3. Joint faces are cleaned back and primed if the sealant needs it.
  4. Backing rod sized to the joint goes in to set the depth.
  5. The exterior sealant is applied, tooled and checked along its length.

Before we arrive

  • Mention if the joints have been sealed before
  • Where the joints are inside, avoid wetting them before we arrive
  • Let us know about stairs, lifts or work at height

Advice

How the job changes by surface

Render joints

Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.

Brickwork movement joints

Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.

How to look after the new joints

No joint lasts for ever, but care makes a real difference. A few tips:

  • Look over the joints every year, ideally after winter
  • Never let anyone fill a movement joint with mortar
  • Have failed joints looked at early
  • Keep water from gutters off the wall

Do not let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.

A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
