External mastic in Upper Kingston, done properly

For buildings in Upper Kingston, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We work on brickwork movement joints, copings & trims and joints between brick and frames, and people most often call us about weeds or debris growing in open joints and sealant that has lost its bond to the brick or render.

In a village or hamlet like Upper Kingston, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.

Every job is covered by our one-year guarantee.

What we’re called out for in Upper Kingston

Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.

People generally contact us when they notice one of these:

  • Leaking joints around cladding and façade panels
  • Sealant pulling away from one side of the joint
  • Joints pointed up with cement by mistake
  • Hard, crazed mastic that has stopped moving

For site and facilities teams at buildings such as Ringwood Junior School, its movement joints, gutters and trims need looking after like any other building’s.

Choosing a sealant specialist

External mastic in Upper Kingston: local notes

The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Avon Tyrrell House (about 2.6 miles south-east) nearby, there’s older building stock in the area around Upper Kingston as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.

In the older streets around Trinity Congregational Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Common questions in Upper Kingston

Will you come out to Upper Kingston?

Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

What guarantee comes with external mastic in Upper Kingston?

Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.

Can you quote for more than one area?

Yes, and it often makes sense. Combining jobs makes good use of the visit.

Will the new joint stand out?

The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. Exterior sealants come in a good range of colours.

Do you work for letting agents?

Yes, regularly. We can quote for several properties at once.

Will the old sealant be removed?

Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.

Do you work for hotels and businesses?

Yes. We’ve worked for hotels, offices and other businesses.

Will you leave a mess?

No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

Different surfaces, different methods

Copings and trims

Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.

Concrete and blockwork

Concrete faces can be dusty and porous, so preparation is key. We prime where the sealant needs it before sealing.

DIY sealant or a professional job?

If you’re 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.

A careful DIYer can reseal a simple joint, 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.

How it works

There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the building in most cases. Somewhere as small as Upper Kingston, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  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. We fit closed-cell backing rod to control the depth.
  5. We apply the sealant, tool it and check the whole run.

Preparing for the visit

  • Mention any sign-in or site rules at work premises
  • Let us know about stairs, lifts or work at height
  • Clear the area around the work

Asking for a quote

What to tell us when you ask for a quote:

  • Access, such as stairs, a lift or height
  • A few photos by email, if you can

Why it’s worth doing now in Upper Kingston

Resealing a run of joints in one go is normally better than patching one at a time. Joints of the same age tend to fail together and it means sorting access once. Where a wall is exposed, as many are in small places like Upper Kingston, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
