Window Mastic in Trolliloes
Window and door frames in Trolliloes need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Cracked sealant at the sill ends
- Black, perished sealant on frames
- Rushed sealant from a window installation
Window mastic in Trolliloes, done properly
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. Typical jobs include sealant in the wrong colour for the frame and mastic that has split away from the wall, on uPVC windows, composite doors and window sills.
Somewhere as small as Trolliloes, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Paint up to the joint, not over it
- Wipe condensation off the frames
- Keep timber frames painted
- Avoid harsh chemicals near the mastic
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just ring 0345 464 0079 or drop us an email.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
Frames and glazing around Trolliloes

In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.

How the visit works
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a morning for a couple of windows and a door. Somewhere as small as Trolliloes, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- 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.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before

Is Trolliloes within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is window mastic in Trolliloes guaranteed?
All our work, in Trolliloes and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do you seal inside as well as outside?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.
Can you do upstairs windows?
Yes, as long as they can be reached safely. Tell us about access when you get in touch and we’ll plan for it.
Can new window sealant be painted?
That depends on the product. Silicone isn’t paintable, but some hybrid sealants are. Tell us if you’re decorating and we’ll choose accordingly.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Can I add another job to the visit?
Yes. Just list everything you need and you’ll get one quote.

- Worn gaskets, brush seals or a door that has dropped
- Broken hinges, locks or handles
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.

Do you need window mastic in Trolliloes?
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
Any of these means the joints need attention:
- Sealant in the wrong colour for the frame
- Mastic that has split away from the wall
- Cracked sealant at the sill ends
- Gaps left after new windows were fitted
In and around Trolliloes, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
