External mastic in Hedgerley Green
Low-level joints can usually be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what access is needed. If you have rain getting behind render or cladding at a joint and cracked joints where brick meets render or frames, we can put it right.
Around Hedgerley Green, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in.
All our work is covered by a 12-month guarantee, wherever you are in Slough.

What happens on the day
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes a few hours for a handful of joints, longer for a whole elevation in most cases. In a small place like Hedgerley Green, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Clear the area around the work
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before

Advice
Landlord and commercial work in Hedgerley Green
We work for landlords and letting agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured for the work.
When to call us in Hedgerley Green
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
These are the problems we are asked about most:
- Water getting into walls through failed joints
- Old sealant gone brittle and cracked
- Movement joints with cracked, split or missing sealant
- Rigid filler in a joint that should flex
For an older house near a landmark such as Parish Church of St Mary the Virgin, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Questions to ask before booking
- Who turns up on the day
- Whether the sealant suits the joint
- What the quote includes, VAT included or not
- Whether all the old sealant comes out first
Your questions about external mastic in Hedgerley Green
Can you help a landlord with a rental near Gerrards Cross station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Can you do external mastic in Hedgerley Green?
Yes, Hedgerley Green is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Can you do several jobs on one visit?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
How do you reach high-level joints?
Each building is different. Tell us the height, the number of joints and what’s below them and we’ll confirm how they can be reached safely.
How much does external mastic cost in Hedgerley Green?
Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.
What do you need from me for a quote?
Let us know what needs doing and where, plus pictures if you have them. We’ll ask anything else we need to know.
What is backing rod for?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides.
Do you seal joints where cladding meets other materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
Walls and rooflines in Hedgerley Green
Historic houses like Cliveden (about 4.5 miles west) are a reminder that the area around Hedgerley Green has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. 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.
If you look after a building such as Gayhurst School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Gerrards Cross station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Why act early in Hedgerley Green
Water gets in through a failed movement joint and can run behind render or cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. In a small place like Hedgerley Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Different surfaces, different methods
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that’s happened, we rake it out and reseal it properly where it can be done safely.

DIY sealant or a professional job?
If you do try it yourself, take your time over the 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.
A DIY attempt does not rule out a professional job. We cut it out and start again.
