Why deal with it now?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. In a small place like Chicheley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

External mastic in Chicheley, done properly
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We take the old material out and do it properly. Typical jobs include weeds or debris growing in open joints and damp patches traced to an open external joint, across brickwork movement joints, concrete & block and render & cladding joints.
External sealant needs dry, clean surfaces, so work around Chicheley is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Chicheley questions
What guarantee comes with external mastic in Chicheley?
All our work, in Chicheley and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Is Chicheley within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
How long does external mastic last?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Every job carries our one-year guarantee.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
How long does external mastic take?
As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Larger jobs naturally take longer.
Are you insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Can you seal joints between render and window frames?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces.
Common problems we fix in Chicheley
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
Any of these means the joints need attention:
- Joints pointed up with cement by mistake
- Movement joints with cracked, split or missing sealant
- Moss and dirt in joints with no sealant left
- Damp patches traced to an open external joint
Homes close to Church of St Lawrence include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Cracking across the wall rather than at a joint
- Structural movement, which needs a surveyor or engineer
- Walls that need new movement joints cut into them

The process
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Chicheley, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Move anything stored near the joints
- Mention any parking rules near the property
- Keep children and pets away from the work area

Advice
What the job involves on each surface
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible year round.
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.
Outside joints around Chicheley
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. Historic houses like Linford Manor (about 3.9 miles south-west) are a reminder that the area around Chicheley has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
For site and facilities teams at buildings such as Sherington Church of England School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
