Signs you need external mastic in Holt Pound
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Common reasons people contact us include:
- Brick movement joints where the sealant has split
- Water getting into walls through failed joints
- Panel joints letting water in
- Sealant pulling away from one side of the joint
If you look after a building such as Rowledge Church of England Controlled Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

External mastic in Holt Pound
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. We are often asked to deal with leaking joints around cladding and façade panels and brick movement joints where the sealant has split, on joints between brick and frames, copings & trims and concrete & block.
External sealant needs dry, clean surfaces, so work around Holt Pound is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.

Holt Pound questions
Will you come out to Holt Pound?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Bentley (Hampshire) station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access.
What should I tell you?
Let us know what needs doing and where. We’ll ask anything else we need to know.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
How much does external mastic cost in Holt Pound?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or send us an email and tell us what needs doing and where.
Should I point up the gap in my brickwork?
No. A mortar-filled joint cannot move, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
Will the new joint stand out?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so it doesn’t stand out.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Ask before painting over external sealant
- Have failed joints looked at early
- Tell anyone working on the walls about the movement joints
- Never let anyone fill a movement joint with mortar
Keep pressure washers away from the sealant. High-pressure water can lift the edges.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
Why it’s worth doing now in Holt Pound
Sealing over the top of old mastic does not hold for long. New sealant does not bond well to old, weathered sealant, so we always take the old sealant out. In a small place like Holt Pound, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
Why us?
- We agree the colour with you first
- We are fully insured
- We leave the area clean and tidy
- Any old sealant cut out fully, not covered over

What affects the cost of external mastic
You will get a clear quote before work begins. It’s based on:
- Access and height
- How many areas need sealing
- Any working-time requirements on site
- The product the joint needs
What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
What we need to know
Photos help, but a description is a good start. Please mention:
- Whether it has been sealed before
- Access, such as stairs, a lift or height
- What’s wrong with the joints now
- The address or postcode of the job
Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job, and we’ll take it from there.
What sealant work cannot fix
To be straight with you, some problems need a different trade:
- Render that’s blown, hollow or coming away
- Cracking across the wall rather than at a joint
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.
What we seal
- Joints between brick and frames
- Render & cladding joints
- Brickwork movement joints
- Concrete & block
- Copings & trims
- Façade panels

London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Farnham Castle (about 2.7 miles north-east) nearby, there’s older building stock in the area around Holt Pound as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
