Rudgwick Window Mastic
Our applicators work in Rudgwick on mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly.
- White mastic on grey or black frames
- Draughty joints inside around the window
- Hard, cracked sealant around windows
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
About our window mastic in Rudgwick
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. Either or both can be done. We work on aluminium frames, window sills and uPVC windows, and the jobs we see most are cracked internal joints between frame and plaster and draughts coming in around windows and doors.
Mastic can only go onto a dry, clean joint, so window work in Rudgwick 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.

How we quote for window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The number and length of the joints
- The old material and how stubborn it is
- Any working-time requirements on site
- The product the joint needs
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- What’s wrong with the joints now
- Whether it’s a home or a business
- Pictures of the joints, sent by email
- Any access issues, like height or stairs
For window mastic in Rudgwick, call 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.
What the job involves on each surface
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.
Composite doors
Front doors take the weather head on. We pay most attention there.
Signs you need window mastic in Rudgwick
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
People normally contact us when they notice something like this:
- Gaps where the sill meets the wall
- Gaps between the frame and the inside reveal
- Rushed sealant from a window installation
- Cold air getting in at the frame edge
If you live in an older home near Holy Trinity Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What to look for in a quote
- Whether the sealant suits the joint
- Whether they seal over old material or remove it
- How the joint is cleaned and prepared
- Whether you can choose the colour

How much does window mastic cost in Rudgwick?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Can you do upstairs windows?
Yes, where they can be reached safely. Tell us about access when you get in touch so we can plan the job.
Will new mastic stop draughts?
It will if the frame joint is the problem. We check where the draught is before work begins.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Can you get sealant to suit coloured frames?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
How the visit works
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes a morning for a couple of windows and a door for a typical job. In a small place like Rudgwick, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Tell us about any water getting in
- Clear items away from the joints we are working on
- Tell us if parking is tricky
