Wormingford External Mastic
Problem with your movement joints in Wormingford? We remove the old material, prepare the joints and seal them properly.
- Brick movement joints where the sealant has split
- Sealant that has lost its bond to the brick or render
- Rain getting behind render or cladding at a joint
External mastic in Wormingford
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two where mortar or filler would crack. We work on brickwork movement joints, joints between brick and frames and render & cladding joints, and the jobs we see most are failed seals between different materials and moss and dirt in joints with no sealant left.
Outside joints can only be sealed when they’re dry, so work in Wormingford is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Signs you need external mastic in Wormingford
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.
Most people get in touch when they notice something like this:
- Sealant that has lost its bond to the brick or render
- Hard, crazed mastic that has stopped moving
- Damp patches traced to an open external joint
- Weeds or debris growing in open joints
Rented homes near Bures station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

How the job changes by surface
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so the sealant in it must stay soft and stretchy.

How the visit works
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Wormingford, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in

What happens if it’s left?
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost near the open joint, so the damage spreads beyond the joint. Where a wall is exposed, as many are in small places like Wormingford, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Keeping the joints in good condition
So the new joints stay in good condition:
- Check external joints each spring
- Wash walls gently around the sealant
- Point out the joints to other trades
- Ask before painting over external sealant
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
