When to call us in Burnham-on-Crouch

Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.

Look out for any of the following:

  • Old sealant gone brittle and cracked
  • Panel joints letting water in
  • Weeds or debris growing in open joints
  • Joints with sealant missing in places

In the older streets around St Mary's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

How we handle external mastic in Burnham-on-Crouch

Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a colour to suit. Typical jobs include leaking joints around cladding and façade panels and water getting into walls through failed joints, on copings & trims, joints between brick and frames and concrete & block.

In a smaller place like Burnham-on-Crouch, some homes face open ground, so exposed walls and rooflines take more wind-driven rain. Joints on those sides are generally the first to go.

A 12-month guarantee comes as standard.

External mastic in Burnham-on-Crouch: local notes

Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

For landlords with property near Burnham-On-Crouch station, outside joints that have cracked can let damp into a rental, so check them between lets. If you look after a building such as Burnham-on-Crouch Primary School, larger buildings have long runs of movement joint that eventually need resealing.

When it isn’t the sealant

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • Walls that need new movement joints cut into them
  • Rising or penetrating damp from elsewhere in the wall
  • Structural movement, which needs a surveyor or engineer

If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before you book.

Surfaces we seal

  • Façade panels
  • Joints between brick and frames
  • Brickwork movement joints
  • Render & cladding joints
  • Concrete & block
  • Copings & trims

Why deal with it now?

Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. In a smaller place like Burnham-on-Crouch, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.

Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.

  • We are fully insured
  • Homes, businesses and hotels

The process

You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours to a few days, depending on the length of joint and the access in most cases. A visit to Burnham-on-Crouch is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. First, the joints are inspected and the access agreed.
  2. Every bit of old sealant and any mortar or debris is cut out.
  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. We apply the sealant, tool it and check the whole run.

How to prepare

  • Keep pets and children clear of the area while we work
  • Move anything stored near the joints
  • Mention if the joints have been sealed before

Advice

Burnham-on-Crouch questions

I let a flat near Burnham-On-Crouch station. Can you help?

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or email us with the details for a clear quote.

Do you cover smaller places like Burnham-on-Crouch?

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

Can you seal joints between two different materials?

Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides, primed where needed.

Can you work on commercial sites?

Yes. Larger jobs can be planned room by room or area by area.

What do you put in the joint?

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

How much does external mastic cost in Burnham-on-Crouch?

Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or drop us an email and let us know what needs doing and where.

Do you use backing rod?

Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.

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 affects the quote in Burnham-on-Crouch

Every job gets its own quote. This is what makes a difference:

  • The product the joint needs
  • How much old sealant there is and how hard it is to remove
  • Mould in or behind the old joints
  • Whether the work is at height

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

What to tell us for a quote

To help us quote quickly, let us know:

  • How we’d reach the joints
  • A few photos by email, if you can
  • Whether it’s a home or a business
  • The problem you’ve noticed

For a quote, phone 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before work begins.

Landlords, agents and businesses in Burnham-on-Crouch

For anyone letting property in or around Burnham-on-Crouch, several properties can go on one quote. Just tell us the addresses and what each one needs, and pictures by email help.

In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.

Should I try it myself first?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
