About our external mastic in Sandwich Bay Estate

We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the joint doesn’t stand out. If you’re dealing with joints where the bead has come unstuck and panel joints letting water in, we can put it right, whatever the surface.

In a village or hamlet like Sandwich Bay Estate, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.

All our work comes with a one-year guarantee.

Looking after it afterwards

Good habits help new joints last longer. Our tips:

  • Avoid pressure-washing directly into sealant joints
  • Act on the first splits you see
  • Deal with leaking gutters that soak the joints below
  • Leave the joints unpainted unless we’ve said otherwise

Do not paint over the new sealant unless we have said the product is paintable. Paint can crack on a flexible joint, and paint can crack as the joint moves.

Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.

What happens if it’s left?

A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Around Sandwich Bay Estate, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Leaving a failed joint usually makes the job bigger, not smaller. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

Questions from Sandwich Bay Estate

Do you work for landlords with property near Sandwich station?

Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.

Does the coastal weather in Sandwich Bay Estate affect outside sealant?

Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.

How long before the joint can be used?

It depends on the product and the temperature. Before we leave, we’ll tell you the cure time.

Can you quote for more than one area?

Yes. Several rooms, windows or areas can go on one quote.

Can you match the colour of my brickwork?

We choose a sealant colour to suit the brick, stone or render so the joint blends in. Exterior sealants come in a good range of colours.

Can I do it myself?

You can, for simple jobs. 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.

Is it OK to fill a movement joint with cement?

No. Rigid materials can’t move with the wall, so the joint stops doing its job. If it has already been filled, we can usually cut it out and reseal it.

Do you guarantee your work?

Yes, for a year. If anything isn’t right with the work within the year, let us know and we will sort it.

How we quote for external mastic

Some jobs are bigger than they look, and some smaller. The main factors:

  • How many areas need sealing
  • The type of sealant required
  • How easy the joints are to reach
  • How much there is to do

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Asking for a quote

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

  • Whether it has been sealed before
  • The rough size of the job
  • Any access issues, like height or stairs
  • The address or postcode of the job

Getting a quote is simple: tell us what needs doing and where. A few photos by email make the job easier to understand, and we’ll come back to you with a quote.

Can I do it myself?

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

What happens on the day

All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. It normally takes anything from a few hours to several days, depending on the building. Somewhere like Sandwich Bay Estate needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  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. The faces are brushed clean and primed where the product requires 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.

Preparing for the visit

  • Mention any parking rules near the property
  • Keep pets and children clear of the area while we work
  • Where the joints are inside, avoid wetting them before we arrive

Getting a quote

We quote each job on its own. Simply phone 0345 464 0079 or drop us an email and describe the job and send photos if you have them.

Advice

Walls and rooflines in Sandwich Bay Estate

Sandwich Bay Estate is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Historic houses like Walmer Castle (about 4.6 miles south) are a reminder that the area around Sandwich Bay Estate has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
