External mastic for homes and businesses in Charing Heath
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing and we use one wherever it does. Common call-outs are for water getting into walls through failed joints and cracked joints where brick meets render or frames, across concrete & block, copings & trims and render & cladding joints.
Somewhere as small as Charing Heath, homes and farm buildings often face open ground, 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.
Every job comes with our one-year guarantee, wherever you are in Kent.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Why deal with it now?
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render around the joint, so the damage spreads beyond the joint. Around Charing Heath, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Expect the work to take anything from a few hours to several days, depending on the building, and we tell you how long to leave it before we go. In a small place like Charing Heath, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.

Advice
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Wash walls gently around the sealant
- Get split or bare joints resealed while the damage is small
- Look over the joints every year, ideally after winter
- Never let anyone fill a movement joint with mortar
Don’t paint over the new sealant unless we’ve said the product is paintable. Many exterior sealants aren’t designed to be painted.
Act while the splits are small. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
How we quote for external mastic
The price is agreed before any work begins. It takes into account:
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- When we can work, for business premises

What external mastic looks like in Charing Heath
With historic houses such as Godinton House (about 4.7 miles south-east) nearby, there’s older building stock in the area around Charing Heath as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Charing station, split movement joints are easy to miss on a rental until damp shows inside. If you live in an older home near Church of the Holy Trinity, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
