DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you are set on DIY, put the effort into 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.
How we handle external mastic in Whiteleaf
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. Common call-outs are for sealant that has lost its bond to the brick or render and movement joints filled with mortar instead of sealant, across façade panels, joints between brick and frames and copings & trims.
In a village or hamlet like Whiteleaf, older cottages and farm buildings often stand in the open, 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.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

How it works
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Whiteleaf, access is generally 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.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height

Why deal with it now?
Water gets in through a failed movement joint and can run behind render or cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. In a small place like Whiteleaf, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before we start.
Why book with us
- Anti-fungal silicone where joints get wet
- We agree the colour with you first
- Old sealant always removed completely
- ARBOMaster approved applicator
When something else is needed
It helps to know what we cannot do too:
- Loose or hollow render, which needs re-rendering
- Cracked brickwork or render that needs a builder or plasterer
- 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.
Joints and surfaces we work on
- Joints between brick and frames
- Copings & trims
- Façade panels
- Brickwork movement joints
- Concrete & block
- Render & cladding joints
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Check the sealant is paintable before painting near it
- Walk round the building once a year and look at the joints
- Don’t let climbing plants root in the sealant
- Have failed joints looked at early
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage.
Walls and rooflines in Whiteleaf
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Monks Risborough CofE Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around Church of St Dunstan, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Rented homes near Monks Risborough station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Do you work at height?

Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
When will the joints need doing again?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year.
What’s an expansion joint in brickwork?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
