What affects the cost of window mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- When we can work, for business premises
- How much there is to do
- Which sealant suits the joint
- Access and height
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and give you a clear price before work begins.
Helping us quote
To help us quote quickly, please include:
- Access, such as stairs, a lift or height
- Roughly how big the job is
- A few pictures by email, if you can

Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant will not do:

What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes most of a day for a typical house, less for a few frames, and the area is left clean. For a village or hamlet like Epwell, 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.
- Each frame is looked over and we agree which ones need resealing.
- 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.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we’re working on

What window mastic looks like in Epwell
Historic houses like Upton House (about 3.3 miles north) are a reminder that the area around Epwell has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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 Anne include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What we are called out for in Epwell
Mastic ages in the weather. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
Keep an eye out for any of the following:
- A bead that does not match the frame
- Gaps left after new windows were fitted
- Black, perished sealant on frames
- Damp patches on the reveal after heavy rain
Around Epwell, as everywhere, window mastic is only as good as the preparation behind it.

Why act early in Epwell
Choosing the product is half the job. Interior caulk and bathroom silicone are not made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Around Epwell, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, 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.

Landlord and commercial work in Epwell
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll quote.
We work for landlords and letting agents as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
