Hurley External Mastic
Our applicators work in Hurley on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Joints where the bead has come unstuck
- Cracked joints where brick meets render or frames
- Failed sealant between panels on a façade
External mastic in Hurley, done properly
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the line blends in. We are often asked to deal with old sealant gone brittle and cracked and failed seals between different materials, on joints between brick and frames, façade panels and render & cladding joints.
Older homes in small places like Hurley may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or send us an email.

Your questions about external mastic in Hurley
Can you do external mastic in Hurley?
Yes. Our work covers London and the South East, and Hurley is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Do you work for landlords with property near Marlow station?
Yes. We work for letting agents and landlords as well as homeowners. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
What is a movement joint?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
When is the sealant fully cured?
Cure times vary by product and the conditions. Before we leave, we’ll tell you the cure time.
What does external mastic cost?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or send us an email and tell us what needs doing and where.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Can you seal joints between two different materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. The sealant is matched to both sides.
What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Hurley, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts

Outside joints around Hurley
With historic houses such as Harleyford Manor (about 0.6 miles north) nearby, there’s older building stock in the area around Hurley 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. 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.
Managing a site like Danesfield School? Then its movement joints, gutters and trims need looking after like any other building’s. In the older streets around Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant.

What’s near Hurley

When to call us in Hurley
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
Any of these means the joints need attention:
- Brick movement joints where the sealant has split
- Cracked joints where brick meets render or frames
- Joints pointed up with cement by mistake
- Panel joints letting water in
Letting a property close to Marlow station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Look over the joints every year, ideally after winter
- Leave the joints unpainted unless we have said otherwise
- Get split or bare joints resealed while the damage is small
- Point out the joints to other trades
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
When it is not the sealant
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Cracked brickwork or render that needs a builder or plasterer
- Failed render or damaged cladding panels
- Structural movement, which needs a surveyor or engineer
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before booking.
Surfaces we seal
- Concrete & block
- Render & cladding joints
- Copings & trims
- Façade panels
- Joints between brick and frames
- Brickwork movement joints
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

What happens if it’s left?
Resealing a run of joints in one go is usually better than patching one at a time. They’ve weathered the same way. In a small place like Hurley, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.
