Bluetown Window Mastic
Window mastic across Bluetown and nearby, with every bit of old sealant taken out first and a one-year guarantee.
- Rushed sealant from a window installation
- Mastic that has split away from the wall
- Mastic that is falling out in pieces
What the job involves on each surface
Aluminium frames
Coated aluminium needs a compatible sealant, and acetoxy silicones are not used, as they can attack some metals. We use a neutral-cure product.
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.
Window mastic for homes and businesses in Bluetown
There are two joints on most windows. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. If you have hard, cracked sealant around windows and gaps between the frame and the inside reveal, we can help, on uPVC windows, window sills and patio & French doors alike.
Mastic can only go onto a dry, clean joint, so window work in Bluetown is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

What sealant work can’t fix
In fairness, some problems need a different trade:
- A failed sealed unit that has misted up
- Faulty window hardware
- Damp coming through the wall itself rather than the frame joint
If you are not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before you book.

What happens if it’s left?
Failed mastic is not a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we’ll say so. Where a wall is exposed, as many are in small places like Bluetown, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
Why us?
- We leave the area clean and tidy
- Full insurance on every job
- An ARBOMaster approved applicator

What window mastic looks like in Bluetown
Historic houses like Belmont House and Gardens (about 4.4 miles east) are a reminder that the area around Bluetown 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. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Milstead and Frinsted Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Sittingbourne station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What we are called out for in Bluetown
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
Most people get in touch when they notice something like this:
- Gaps where the sill meets the wall
- Black, perished sealant on frames
- Draughty joints inside around the window
- Sealant in the wrong colour for the frame
For an older house near a landmark such as Church of St Catherine, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

The process
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before work begins. The work normally takes a few hours for a few frames, or a day or more for a whole house. Somewhere like Bluetown needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- 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
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises
