Window mastic for homes and businesses in Boxford
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. Typical jobs include draughts coming in around windows and doors and water coming in at the bottom corners of a door, across patio & French doors, window sills and aluminium frames.
Mastic can only go onto a dry, clean joint, so window work in Boxford is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Whatever the size of the job, you get the same one-year guarantee in Boxford and across West Berkshire.

When it isn’t the sealant
New sealant cannot fix everything, and we’ll tell you before work begins. Sealant won’t put right:
- Damp problems in the wall away from the window
- Soft or decayed wood in the frame
- A failed sealed unit that has misted up
If in doubt, phone 0345 464 0079 or email us and we will say what we think.

Questions from Boxford
I let a flat near Kintbury station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Boxford?
Yes. Boxford is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Is the work guaranteed?
Yes, with our one-year guarantee. A yearly look at the joints helps them last.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Where are you based?
We work from Crawley. We cover Boxford and the rest of West Berkshire, along with the rest of our area.
How the visit works
We keep the work tidy and contained to the joints we’re treating. Expect the work to take a few hours for a handful of frames, longer for a whole house, and we tell you how long to leave it before we go. Somewhere as small as Boxford, 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.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
Before we arrive
- Clear items away from the joints we’re working on
- On commercial sites, let us know about site rules
- Tell us if parking is tricky

Advice
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Use gentle cleaners on frames and sealant
- Keep drainage slots and sill grooves clear
- Don’t paint over the silicone
- Check the mastic once a year
Most silicone sealants will not take paint, so mention any painting plans before any work starts. We can use a paintable sealant where that matters.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.

Window mastic in Boxford: 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. Historic houses like Benham Park (about 2.5 miles south) are a reminder that the area around Boxford 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’s traditional sand mastic.
For landlords with property near Kintbury station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

When to call us in Boxford
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
The problems people usually mention when they call include:
- Black, perished sealant on frames
- Cold air getting in at the frame edge
- Water coming in at the bottom corners of a door
- Gaps left after new windows were fitted
If you live in an older home near Parish Church of St Andrew, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Before you book anyone
- How the joint is cleaned and prepared
- Whether all the old sealant comes out first
- When the joint can take water or movement
- Are they insured?
What the job involves on each surface
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the new bead is laid against the frame and the wall.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour suits the frame.
