How we handle window mastic in Lexden
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on uPVC windows, patio & French doors and aluminium frames, and the jobs we see most are whistling draughts around closed windows and sealant in the wrong colour for the frame.
Many houses in smaller places like Lexden have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
Whatever the size of the job, you get the same one-year guarantee in Lexden and across Essex.

Windows and doors in Lexden
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Church of St Leonard include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in. Managing a site like Philip Morant School and College? Then its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Colchester station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What’s near Lexden

Looking after it afterwards
Looking after new joints is easy:
- Check the mastic once a year
- Avoid harsh chemicals near the mastic
- Keep timber frames painted
- Don’t paint over the silicone
Most silicone sealants will not take paint, so mention any painting plans before work begins. There are paintable sealants for joints that need it.
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.
How we quote for window mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Working hours on commercial sites
- How many areas need sealing
- The size of the job
- Whether old sealant or filler has to be cut out
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.
What to tell us for a quote
When you contact us, it’s useful to know:
- What’s wrong with the joints now
- Whether it’s a home or a business
- Any previous sealing or DIY work
- How we’d reach the joints
Every job is quoted individually, so the first step is telling us about yours. Simply call 0345 464 0079 or send us an email and describe the job, and pictures are welcome.
What happens on the day
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from an hour or two to a full day, depending on how many frames there are. Parking around Lexden is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We start by checking each window and door with you.
- 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.
- Finally we tidy up and check each joint.
How to prepare
- For business premises, tell us about site rules or sign-in
- Clear the area around the work
- Mention any parking rules near the property

Advice
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A door that needs adjusting, rehanging or new seals
- Damp coming through the wall itself rather than the frame joint
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before you book.
Joints and surfaces we work on
- Aluminium frames
- Composite doors

Why act early in Lexden
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly. Around Lexden, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
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.
