Window Mastic in Weddington
Our applicators work in Weddington on mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.
- Mastic that’s falling out in pieces
- Sealant in the wrong colour for the frame
- Gaps left after new windows were fitted
The process
On the day, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. The work generally takes a few hours for a few frames, or a day or more for a whole house. In a small place like Weddington, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry, 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.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts

Window mastic for homes and businesses in Weddington
Most frames have an outside joint and an inside one. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. If you have untidy mastic left by window fitters and cold air getting in at the frame edge, we can put it right, on window sills, composite doors and patio & French doors alike.
Somewhere as small as Weddington, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
All our work comes with our one-year guarantee.

Windows and doors in Weddington
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Goodnestone Park (about 3.9 miles south-west) are a reminder that the area around Weddington has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For site and facilities teams at buildings such as Ash Cartwright and Kelsey Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Sandwich station, renewing tired window mastic between tenants heads off draught and damp complaints.

Quotes for window mastic in Weddington
Every job gets its own quote. This is what makes a difference:
- The product the joint needs
- Working hours on commercial sites
- Access and height
- Whether old sealant or filler has to be cut out
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
Helping us quote
Before you ask for a quote, have a think about:
- What the problem is, such as mould, gaps, leaks or cracking
- Any previous sealing or DIY work
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we will talk you through the work before giving you a price.
Keeping the joints in good condition
So the new joints stay in good condition:
- Keep drainage slots and sill grooves clear
- Keep solvents and bleach off the sealant
- Do not paint over the silicone
- Air rooms to keep condensation down around windows
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just ring 0345 464 0079 or email us.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
Why deal with it now?
A quick bead over the top of old mastic looks like an easy fix, but new sealant cannot bond to old, crumbling mastic. It peels before long, and water still gets in behind. The old mastic has to come out. Where a wall is exposed, as many are in small places like Weddington, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Leaving a failed joint generally makes the job bigger, not smaller. If you are not sure whether it needs doing, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

What else we do in Weddington
What we are called out for in Weddington
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
Any of these means the joints need attention:
- A bead that doesn’t match the frame
- Rain getting in at the frame or under the sill
- Leaking joints at the ends of sills
- Untidy mastic left by window fitters
In the older streets around Church of St Nicholas, the joint between an old wall and a newer frame is generally the first place rain gets in.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you when we finish.
