Winkfield: your questions answered
Can you do external mastic in Winkfield?

I let a flat near Ascot station. Can you help?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Do you have insurance?
Yes. We are fully insured.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you.
How often do external joints need resealing?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away.
External mastic in Winkfield
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. We’re often asked to deal with movement joints with cracked, split or missing sealant and water getting into walls through failed joints, on render & cladding joints, brickwork movement joints and façade panels.
In a village or hamlet like Winkfield, 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.
Every job is covered by our 12-month guarantee.

Landlord and commercial work in Winkfield
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
How we quote for external mastic
The price is agreed before any work begins. It takes into account:
- The type of sealant required
- Working hours on commercial sites
- The number and length of the joints
- The number of rooms or windows
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear price before we start.

Photos help, but a description is a good start. Please mention:
- The type of property
- How we’d reach the joints
- Roughly how big the job is

Asking for a quote is easy: let us know the job and the location. A few pictures by email make the job easier to understand, and we will take it from there.
Outside joints around Winkfield
With historic houses such as St Leonard's Hill (about 2.7 miles north-east) nearby, there’s older building stock in the area around Winkfield 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. 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.
Homes close to Church of St Mary include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. For landlords with property near Ascot station, outside joints that have cracked can let damp into a rental, so check them between lets.

Keeping the joints in good condition
So the new joints stay in good condition:
- Act on the first splits you see
- Check external joints each spring
- Never let anyone fill a movement joint with mortar
- Show decorators and builders where the movement joints are
Do not let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Act while the splits are small. Then it’s a straightforward cut-out and reseal.
Surface by surface
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out and protects the render itself.
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two so neither cracks the other.
Common problems we fix in Winkfield
Using the wrong sealant is another common reason. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.
If you can see any of these, it’s time to have the joints looked at:
- Joints with sealant missing in places
- Plants rooting in failed movement joints
- Sealant that has lost its bond to the brick or render
- Old sealant gone brittle and cracked
Schools such as Winkfield St Mary's CofE Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.
What your quote should include
- Is the old sealant removed completely?
- Are they insured?
- How long to leave it before use
- Which sealant they’ll use, and why
How the visit works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. It normally takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Winkfield, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed
