Window mastic for homes and businesses in Colchester
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. Our applicators cut it out and replace it with a flexible, weatherproof sealant. If you have draughty joints inside around the window and leaking joints at the ends of sills, we can put it right.
In Colchester, windows range from older timber frames to modern uPVC and aluminium. The mastic around all of them ages, and it’s generally the first thing to let the weather in.
You are covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or drop us an email.
Honest limits
To be straight with you, there are a few things sealant will not fix:
- A door that needs adjusting, rehanging or new seals
- Damp problems in the wall away from the window
- A failed sealed unit that has misted up

Colchester homes and the weather
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 let a flat or house near Colchester Town station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For an older house near a landmark such as Church of St Peter, the joint between an old wall and a newer frame is normally the first place rain gets in.

Different surfaces, different methods
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain can’t run into the wall.
Composite doors
Draughts round the door leaf normally come from worn seals or adjustment, not the mastic. We will tell you if that is what we find.

How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes most of a day for a typical house, less for a few frames, and the area is left clean. Where a business in Colchester needs to stay open, out-of-hours working can be arranged, and homes are booked within our usual hours, Monday to Saturday.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- 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.

Why deal with it now?
Failed mastic isn’t 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. In a busy place like Colchester, a failed joint in a flat or office can send water into the space below, where it’s often found late and is bigger to put right.
Combining jobs into one visit usually makes better use of the time than several visits. We’ll give you a clear quote for the lot.
Why us?
- We never seal over old sealant
- Sanitary silicone with an anti-fungal additive in wet areas
- Neat joints and a tidy finish
- An ARBOMaster approved applicator

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
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.
What we are called out for in Colchester
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar never bonded as it should, and it lets go sooner than it should.
The most common problems we see are:
- Cold air getting in at the frame edge
- Cracked sealant at the sill ends
- Sealant in the wrong colour for the frame
- Rain getting in at the frame or under the sill
Schools such as Colchester Sixth Form College are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
Before booking anyone
- Are they insured?
- Whether the sealant suits the joint
- What preparation is included
- How long the guarantee is
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Avoid harsh chemicals near the mastic
- Keep jet washers away from the mastic
- Keep drainage slots and sill grooves clear
- Look round the frames every year or so
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
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.
