Common questions in Durley
I let a flat near Hedge End station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Can you do external mastic in Durley?
Yes. We work across London and the South East, and Durley is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing.
Are you fully insured?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
What is a movement joint?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
External mastic in Durley
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. We work on concrete & block, façade panels and joints between brick and frames, and people most often call us about weathered mastic that no longer stretches and movement joints with cracked, split or missing sealant.
In a village or hamlet like Durley, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Each job carries a 12-month guarantee.

Surface by surface
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. A primer goes on where the product requires one.
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out and helps it last.
What affects the quote in Durley
For a quick quote, just ask. The main things that affect it are:
- Which sealant suits the joint
- When we can work, for business premises
- Any mould that needs treating
- The amount of work
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- A few pictures by email, if you can
- Where the job is, and your postcode
- How many joints, rooms or windows are involved
- Whether it’s a home or a business
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
External mastic in Durley: local notes
With historic houses such as South Stoneham House (about 5 miles west) nearby, there’s older building stock in the area around Durley as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Church of the Holy Cross, older walls, gutters and the joints where extensions meet them need a flexible sealant. Letting a property close to Hedge End station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Durley is about 3 miles north-east of Hedge End, in Hampshire. Durley gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a one-year guarantee. Durley is one of 683 places in Hampshire we cover for external mastic. We also work in Southampton, around 6 miles away.
Every address in SO32 is within our area for external mastic. That includes homes and businesses on Kytes Lane, The Sawmills and White Gates and the roads around them. Neighbouring places we cover for external mastic include Boorley Green (1 mile south-west), Durley Street (1 mile north-east), Wintershill (1 mile north), Horton Heath (2 miles west) and Curdridge (2 miles south-east).

Local landmarks in Durley
Locally, jobs take us to homes and businesses close to Wyvern Technology College, among other places. For rail, the closest station is Hedge End station, about 1.6 miles south-west. Nearby you will also find Bishop's Waltham Museum (2.2 miles east) and Moorgreen Hospital (2.8 miles south-west). Green spaces nearby include Bishops Waltham Branch LNR.
When to call us in Durley
Using the wrong sealant is another common reason. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
Signs it’s time to call us include:
- Movement joints filled with mortar instead of sealant
- Joints where the bead has come unstuck
- Brick movement joints where the sealant has split
- Weathered mastic that no longer stretches
For site and facilities teams at buildings such as Durley Church of England Controlled Primary School, larger buildings have long runs of movement joint that eventually need resealing.

How the visit works
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on the building, and we tell you how long to leave it before we go. Somewhere as small as Durley, access is often the only tricky part. 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.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Let us know about parking restrictions
- Mention if the joints have been sealed before

If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.
Surfaces we seal

Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. In a small place like Durley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on how much there is to do, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

Looking after it afterwards
After the cure time, these simple habits help:
- Wash walls gently around the sealant
- Check external joints each spring
- Tell anyone working on the walls about the movement joints
- Keep movement joints as flexible joints, not mortar
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.
