What affects the cost of external mastic
The quote reflects the job in front of us. We take into account:
- The type of sealant required
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
To make quoting easier, let us know:
- If it’s domestic, commercial or a hotel
- How many joints, rooms or windows are involved
- What’s wrong with the joints now
- How we’d reach the joints
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To get started, ring 0345 464 0079 or send us an email.
External mastic for homes and businesses in Spencers Wood
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement. We work on copings & trims, brickwork movement joints and concrete & block, and people most often call us about plants rooting in failed movement joints and rain getting behind render or cladding at a joint.
In a smaller place like Spencers Wood, some homes face open ground, and walls and rooflines facing the weather take the worst of it. Joints on those sides are generally the first to go.
Each job carries a 12-month guarantee, large or small.

Spencers Wood buildings and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Stratfield Saye House (about 3.3 miles south) nearby, there’s older building stock in the area around Spencers Wood as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Rented homes near Reading Green Park station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Why act early in Spencers Wood
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render around the joint, so the damage spreads beyond the joint. In an older home around Spencers Wood, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.

Landlord and commercial work in Spencers Wood
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
How to look after the new joints
A little care helps the new joints last. We recommend:
- Have failed joints looked at early
- Do not let climbing plants root in the sealant
- Keep high-pressure jets off the joints
- Make sure movement joints are not pointed over
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.
Act while the splits are small. At that stage it’s a simple cut out and reseal before water has had years to get in.
Spencers Wood: your questions answered
Can you help a landlord with a rental near Reading Green Park station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Is Spencers Wood in your area for external mastic?
Yes. Our work covers London and the South East, and Spencers Wood is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Should I point up the gap in my brickwork?
No, not where the gap is a movement joint. Filling it with mortar defeats its purpose and can lead to cracking. A flexible sealant is the right fill.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we are using and why.
What we are called out for in Spencers Wood
Some movement joints have been pointed up with mortar. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Keep an eye out for these signs:
- Sealant pulling away from one side of the joint
- Brick movement joints where the sealant has split
- Panel joints letting water in
- Cracked joints where brick meets render or frames
For an older house near a landmark such as St Michael and All Angels, an extension built onto an older house moves differently, and the joint between them takes the strain.

- When the joint can take water or movement

The work normally takes anything from a few hours to several days, depending on the building, depending on the size of the job.
