Crockleford Heath Window Mastic
We cover Crockleford Heath for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Gaps where the sill meets the wall
- Draughts coming in around windows and doors
- Untidy mastic left by window fitters
The process
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take most of a day for a typical house, less for a few frames. In a small place like Crockleford Heath, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Tell us about any water getting in
- Keep children and pets away from the work area
- Move anything stored near the joints

Window mastic in Crockleford Heath, done properly
Frames and walls do not move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. Common call-outs are for untidy mastic left by window fitters and leaking joints at the ends of sills, across window sills, patio & French doors and uPVC windows.
Outdoor sealant needs dry, clean surfaces, so work on frames around Crockleford Heath is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Our work is backed for twelve months.

Crockleford Heath: your questions answered
Is Crockleford Heath in your area for window mastic?
Yes. Our work covers London and the South East, and Crockleford Heath is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear quote.
Is Crockleford Heath within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
How many windows can you do in a day?
A handful of frames is a short visit. You’ll get a timescale with the quote.
Do you seal inside as well as outside?
Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.
Is the new sealant paintable?
Not if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can you seal over the old sealant?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Why it’s worth doing now in Crockleford Heath
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. In a small place like Crockleford Heath, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.
Why us?
- Approved under the ARBOMaster scheme
- Old sealant always removed completely
- Sealant colour chosen to suit
- Tidy, careful work
Crockleford Heath homes and the weather
Historic houses like Castle House (about 3.7 miles north) are a reminder that the area around Crockleford Heath has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Hythe station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you look after a building such as Colchester Academy, its window and door frames need their mastic kept sound, just like a home’s.

Do you need window mastic in Crockleford Heath?
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
The problems people normally mention when they call are:
- Rain getting in at the frame or under the sill
- Draughts coming in around windows and doors
- Cracked sealant at the sill ends
- Cracked or shrunken mastic around the frame
Castle House, about 3.7 miles north, is one of the historic houses in the wider area around Crockleford Heath.

What else we do in Crockleford Heath
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Hotels need rooms back in use, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Walk round the house once a year and look at the joints
- Wipe condensation off the frames
- Keep solvents and bleach off the sealant
- Paint up to the joint, not over it
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
