External mastic in Hazeley
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what’s needed to reach them safely. We work on concrete & block, render & cladding joints and copings & trims, and common reasons people get in touch are leaking joints around cladding and façade panels and rain getting behind render or cladding at a joint.
Outside joints can only be sealed when they’re dry, so work in Hazeley is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Each job carries a 12-month guarantee, whatever its size.

How the visit works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the building. Somewhere as small as Hazeley, access is often the only tricky part. 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.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints
- Move anything stored near the joints

Advice
What the job involves on each surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Tell us what the building has when you get in touch.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.

Why it’s worth doing now in Hazeley
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Around Hazeley, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or email us and we will talk you through it.

Your questions about external mastic in Hazeley
Do you cover Hazeley for external mastic?
Yes. We work across London and the South East, and Hazeley is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we will give you a clear quote.
Can you help a landlord with a rental near Winchfield station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Will the new joint stand out?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render so the joint doesn’t draw the eye.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures.
Are you insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can new sealant go over the old?
No. We remove every bit of old sealant first.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Walls and rooflines in Hazeley
Historic houses like Stratfield Saye House (about 3.1 miles north-west) are a reminder that the area around Hazeley has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Mattingley Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. Rented homes near Winchfield station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

Looking after it afterwards
Aftercare is simple:
- Have failed joints looked at early
- Check the sealant is paintable before painting near it
- Don’t let climbing plants root in the sealant
- Look over the joints every year, ideally after winter
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
When it isn’t the sealant
New sealant cannot fix everything, and we’ll tell you before work begins. Sealant will not put right:
- Adding movement joints to masonry that has none
- Cracked brickwork or render that needs a builder or plasterer
- Movement that’s more than a sealant joint can take
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before booking.
