How we handle window mastic in Deans
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on timber windows & doors, patio & French doors and uPVC windows, and people most often call us about draughts coming in around windows and doors and rain getting in at the frame or under the sill.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Why act early in Deans
Not every sealant suits a window. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. In an older home around Deans, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.

How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It normally takes a morning for a couple of windows and a door. Around Deans, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Let us know about stairs, lifts or work at height
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive

Advice
Frames and glazing around Deans
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. With historic houses such as Howden House (about 1.5 miles south-east) nearby, there’s older building stock in the area around Deans as well as newer homes. 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.
If you look after a building such as Deans Community High School, larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Livingston North station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, and a gap filled solid cannot flex. Backing rod sets the right depth.
Common reasons people contact us include:
- Cold air getting in at the frame edge
- Water coming in at the bottom corners of a door
- White mastic on grey or black frames
- Gaps left after new windows were fitted
Historic houses such as Howden House, about 1.5 miles south-east, show how far back building around Deans goes.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Different surfaces, different methods
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
