Elsted: your questions answered
Is window mastic in Elsted guaranteed?
All our work, in Elsted and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Will you come out to Elsted?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses, and we are fully insured.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Elsted.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Will new mastic stop draughts?
Yes, if the air is getting in around the frame. If it’s coming through the window seals, we will tell you.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
How we handle window mastic in Elsted
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. We’re often asked to deal with cold air getting in at the frame edge and mastic that has split away from the wall, across composite doors, aluminium frames and uPVC windows.
Mastic can only go onto a dry, clean joint, so window work in Elsted is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
When it isn’t the sealant
To be straight with you, some problems need a different trade:
- Condensation trapped between the panes
- Penetrating damp from a failed cavity tray or render
- A frame that has rotted at the joint
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.
What we seal
- Aluminium frames
- Composite doors
- Patio & French doors
- uPVC windows
- Timber windows & doors
- Window sills
What affects the quote in Elsted
We quote each job individually. These are the things that affect it:
- The size of the job
- Which sealant suits the joint
- Working hours on commercial sites
- How many rooms, windows or areas are involved
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
What to tell us for a quote
You don’t need to know the technical terms. Just tell us:
- Where the job is, and your postcode
- The type of property
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To get started, phone 0345 464 0079 or email us.
What else we do in Elsted
How the visit works
You do not need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of frames, longer for a whole house in most cases. Somewhere as small as Elsted, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- 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.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed
Getting a quote
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.
Advice
Landlords, agents and businesses in Elsted
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Window mastic in Elsted: local notes
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Uppark (about 2.7 miles south-west) nearby, there’s older building stock in the area around Elsted as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near The Parish Church of St Paul, the joint between an old wall and a newer frame is usually the first place rain gets in. In and around Elsted, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Why it’s worth doing now in Elsted
If you are painting or rendering, reseal at the same time. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Where a wall is exposed, as many are in small places like Elsted, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
Why book with us
- White, clear, grey or another colour, product permitting
- Full insurance on every job
- Any old sealant cut out fully, not covered over
- We agree the colour with you first

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Don’t use solvent cleaners on the joint
- Avoid blasting the frames with a pressure washer
- Walk round the house once a year and look at the joints
- Keep drainage slots and sill grooves clear
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Leaks generally show up in wet, windy weather, 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.
