What affects the cost of external mastic
Jobs vary more than people expect. The main factors:
- The type of sealant required
- How many areas need sealing
- Any mould that needs treating
- Whether the work is at height
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

External mastic for homes and businesses in Lower Eashing
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. If you are dealing with joints pointed up with cement by mistake and joints with sealant missing in places, we can help, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Lower Eashing is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Your questions about external mastic in Lower Eashing
Is Lower Eashing within the area you cover?
Yes, Lower Eashing is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Godalming station. Can you help?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Should I try DIY first?
Sometimes. 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.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
Should I point up the gap in my brickwork?
No. Cement or mortar can’t stretch and the joint fails. Where a joint has been mortared, it can often be raked out and sealed properly.
Are you fully insured?
Yes. We’re fully insured.
Is there a guarantee?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
Outside joints around Lower Eashing
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. With historic houses such as Loseley Park (about 2.7 miles north-east) nearby, there’s older building stock in the area around Lower Eashing as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Homes close to Church of St Mary include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Rented homes near Godalming station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

When something else is needed
New sealant can’t fix everything, and we’ll tell you before we start. Sealant won’t put right:
- Cracking across the wall rather than at a joint
- Loose or hollow render, which needs re-rendering
- Walls that need new movement joints cut into them
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.
Surfaces we seal
- Render & cladding joints
- Façade panels
- Copings & trims
- Concrete & block
- Joints between brick and frames
- Brickwork movement joints
Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
How the visit works
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work starts. Most jobs take anything from a few hours to several days, depending on the building. Somewhere as small as Lower Eashing, access is often the only tricky part. 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.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks
- Keep children and pets away from the work area

Related advice
Surface by surface
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
Signs you need external mastic in Lower Eashing
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
Any of these means the joints need attention:
- Movement joints filled with mortar instead of sealant
- Failed sealant between panels on a façade
- Plants rooting in failed movement joints
- Gaps where render, brick and frames meet
Schools such as St Mary's CofE Voluntary Controlled Infant School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
