The process
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Farleigh Wallop, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Mention if the joints have been sealed before
- For business premises, tell us about site rules or sign-in
- Mention any tricky access

Related advice
What external mastic looks like in Farleigh Wallop
Historic houses like Hall Place (about 5 miles south-east) are a reminder that the area around Farleigh Wallop has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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.
Homes close to Church of St. Andrew include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Rented homes near Basingstoke station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Cracks in the bricks or render themselves, away from the joints
- Render that is blown, hollow or coming away
- Rising or penetrating damp from elsewhere in the wall
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.

What we’re called out for in Farleigh Wallop
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it can’t stretch and tears as soon as the joint widens.
The problems people generally mention when they call are:
- Panel joints letting water in
- Water getting into walls through failed joints
- Brick movement joints where the sealant has split
- Hard, crazed mastic that has stopped moving
If you look after a building such as Brighton Hill Community School, larger buildings have long runs of movement joint that eventually need resealing.

Different surfaces, different methods
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. A primer goes on where the product requires one.
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. In a small place like Farleigh Wallop, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
