About our window mastic in Pevensey
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. If you have mastic that has split away from the wall and water coming in at the bottom corners of a door, we can help.
Mastic can only go onto a dry, clean joint, so window work in Pevensey is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
There’s a 12-month guarantee on every job, large or small.

What window mastic looks like in Pevensey
Pevensey is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Pevensey and Westham CofE Primary School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around St. Nicolas Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Pevensey Bay station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Pevensey is about 3 miles north-east of Eastbourne, in East Sussex.

How the job changes by surface
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. Those corners get the most care.
How we quote for window mastic
The quote reflects the job in front of us. We look at:
- The number and length of the joints
- Whether the work is at height
- Working hours on commercial sites
- The type of sealant required
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.
Helping us quote
What to tell us when you ask for a quote:
- The problem you’ve noticed
- The type of property
- Where the job is, and your postcode
- Any previous sealing or DIY work
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What happens if it’s left?
Not every sealant suits a window. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. In a small place like Pevensey, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

How the visit works
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work starts. The work usually takes most of a day for a typical house, less for a few frames. For a village or hamlet like Pevensey, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we are working on

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Check the mastic once a year
- Wipe condensation off the frames
- Paint up to the joint, not over it
- Keep jet washers away from the mastic
Silicone can’t usually be painted, so mention any painting plans before work begins. We can use a paintable sealant where that matters.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
