Thorrington Window Mastic
Mastic around window and door frames, sills and patio doors for homes and businesses in Thorrington and across Essex. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Draughts coming in around windows and doors
- Gaps where the sill meets the wall
- Damp patches on the reveal after heavy rain
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A DIY attempt does not rule out a professional job. We cut it out and start again.
Window mastic in Thorrington, done properly
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through and quietens the whistle on windy days. If the draught is through the window seals instead, we will tell you. Common call-outs are for leaking joints at the ends of sills and rain getting in at the frame or under the sill, on window sills, composite doors and aluminium frames.
In a village or hamlet like Thorrington, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

How we quote for window mastic
The quote reflects the job in front of us. We look at:
- Whether the work is at height
- Working hours on commercial sites
- The number and length of the joints
- The type of sealant required
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we’ll go through it with you.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Where the property is
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we will come back to you with a quote.
Thorrington questions
Is window mastic in a coastal place like Thorrington any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Will you come out to Thorrington?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Will new mastic stop draughts?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that’s a different fix, and we will say so.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
How the visit works
The work is kept neat and contained to the joints we are treating, so you can get on with your day. Expect the work to take most of a day for a typical house, less for a few frames, and we explain the cure time before we leave. Somewhere as small as Thorrington, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
How to prepare
- Mention any tricky access
- Tell us about any water getting in
- Mention any parking rules near the property

Aftercare tips
A little care helps the new joints last. We recommend:
- Wipe condensation off the frames
- Paint up to the joint, not over it
- Wash the frames with mild soapy water
- Keep paint and stain on wooden frames in good order
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. Resealing closes it.
Signs you need window mastic in Thorrington
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar never bonded as it should, so it comes away long before its time.
People normally contact us when they notice one of these:
- Draughts coming in around windows and doors
- Water coming in at the bottom corners of a door
- Cracked internal joints between frame and plaster
- Rushed sealant from a window installation
Letting a property close to Great Bentley station? Then renewing tired window mastic between tenants heads off draught and damp complaints.
What to look for in a quote

What the job involves on each surface
Composite doors
Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We will tell you if that’s what we find.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.

What else we do in Thorrington
What window mastic looks like in Thorrington
Thorrington is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St Mary Magdelene, the joint between an old wall and a newer frame is generally the first place rain gets in. If you look after a building such as Colne Community School and College, its window and door frames need their mastic kept sound, just like a home’s.
