External mastic for homes and businesses in Little Kimble
On houses, flats and commercial buildings across Little Kimble, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We are often asked to deal with brick movement joints where the sealant has split and weeds or debris growing in open joints, across render & cladding joints, brickwork movement joints and joints between brick and frames.
Older homes in small places like Little Kimble may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Why act early in Little Kimble
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and doesn’t last, so it pays to do it properly once. In a small place like Little Kimble, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first.

How long does external mastic take?
It depends on the size of the job, but as a guide it takes anything from a few hours to several days, depending on the building. We will tell you when we quote.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
What is backing rod for?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only.
Can you seal joints between render and window frames?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides.

Signs you need external mastic in Little Kimble
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
The problems people normally mention when they call include:
- Joints with sealant missing in places
- Weathered mastic that no longer stretches
- Movement joints filled with mortar instead of sealant
- Plants rooting in failed movement joints
For an older house near a landmark such as Church of All Saints, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
