Window mastic in White Colne: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Earls Colne Primary School and Nursery, its window and door frames need their mastic kept sound, just like a home’s. In the older streets around Parish Church of St Andrew, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Chappel & Wakes Colne station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

What happens if it’s left?
Not every sealant suits a window. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. In a small place like White Colne, homes can be exposed to wind and rain, which finds any gap, 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, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

Landlord and commercial work in White Colne
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.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
What happens on the day
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take most of a day for a typical house, less for a few frames. In a small place like White Colne, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height

Advice
How to look after the new joints
So the new joints stay in good condition:
- Keep solvents and bleach off the sealant
- Don’t aim a pressure washer at the joints
- Repaint timber before it’s bare
- Paint up to the joint, not over it
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just ring 0345 464 0079 or email us.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.
What the job involves on each surface
Aluminium frames
Aluminium needs a sealant that bonds to coated metal and we avoid acetoxy silicones, which can react with some metals. Neutral-cure sealant is the safe choice.
Timber windows & doors
Timber moves with moisture as well as heat, so the joint must stay flexible. The paint or stain needs to be sound where the sealant meets it.

Can I do it myself?

When it is not the sealant
To be straight with you, there are a few things sealant won’t fix:
- Damp problems in the wall away from the window
- A sash or casement that won’t close properly
- Rotten timber, which needs a joiner first
