Alfold Crossways homes and the weather

How we handle window mastic in Alfold Crossways
Around Alfold Crossways we seal all kinds of frames: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We’re often asked to deal with draughty joints inside around the window and mastic that has split away from the wall, across timber windows & doors, composite doors and uPVC windows.
Somewhere as small as Alfold Crossways, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Big or small, you get the same one-year guarantee.

Also in Alfold Crossways
Different surfaces, different methods
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
Timber windows & doors
Soft or rotten wood cannot be sealed successfully. If we find rot, we’ll tell you before going ahead, as a joiner will need to deal with it.
Why act early in Alfold Crossways
Running fresh sealant over the old joint is tempting, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Where a wall is exposed, as many are in small places like Alfold Crossways, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Doing several joints on one visit normally makes better use of the time than several visits. You will get one clear quote for the whole job.

When it isn’t the sealant
It helps to know what we can’t do too:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Draughts through the window seals rather than the frame
- Broken hinges, locks or handles
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.
What we seal
- Window sills

- Patio & French doors
- Timber windows & doors
- uPVC windows
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Make sure the drainage slots are not blocked
- Avoid harsh chemicals near the mastic
- Keep timber frames painted
- Don’t paint over the silicone
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
Work for landlords, hotels and businesses
We work for landlords and agents as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
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 that we can handle for you.
The process
A visit follows a simple pattern: we look at the joints together, 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. Somewhere as small as Alfold Crossways, access is often the only tricky part. 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.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Mention if the joints have been sealed before
- Keep children and pets away from the work area
- On commercial sites, let us know about site rules

What affects the quote in Alfold Crossways
The price is agreed before any work begins. It’s based on:
- Access and height
- The number and length of the joints
- Any working-time requirements on site
- Mould in or behind the old joints
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.
What we need to know
You do not need to know the technical terms. Just tell us:
- What’s wrong with the joints now
- Photos by email, if that’s easy
- Whether it’s a home or a business
- Where the property is
Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we will take it from there.

Is there a guarantee on window mastic in Alfold Crossways?
All our work, in Alfold Crossways and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
What sealant do you use?
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’re using.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Can landlords and businesses book you?
Yes. We work in homes, commercial premises and hotels, and we are fully insured.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
