Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Wipe condensation off the frames
- Keep solvents and bleach off the sealant
- Keep drainage slots and sill grooves clear
- Do not paint over the silicone
Keep the new mastic undisturbed while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
How we handle window mastic in Rushden
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we’ll tell you. Typical jobs include rushed sealant from a window installation and damp patches on the reveal after heavy rain, across window sills, aluminium frames and timber windows & doors.
Around Rushden, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Big or small, you get the same 12-month guarantee in Rushden and across Hertfordshire.

Common problems we fix in Rushden
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, so it comes away long before its time.
These are the problems we’re asked about most:
- Cracked sealant at the sill ends
- Mastic that is falling out in pieces
- Hard, cracked sealant around windows
- Draughts coming in around windows and doors
If you live in an older home near Church of St Mary, the joint between an old wall and a newer frame is usually the first place rain gets in.

What the job involves on each surface
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
Aluminium frames
Coated aluminium needs a compatible sealant. We use a neutral-cure product.
Common questions in Rushden
Is Rushden within the area you cover?
Yes, Rushden is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you do window mastic in Rushden?
Yes, Rushden is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear price.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can you do upstairs windows?
Generally, yes. Access is planned before work begins.
Can tenants book the work?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Do you have insurance?
Yes. We are fully insured for domestic and commercial work.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
What happens on the day
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes most of a day for a typical house, less for a few frames. For a village or hamlet like Rushden, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we are working on
- Let us know if you’ve seen damp or leaks

Why deal with it now?
Draughts and leaks don’t always mean new windows. If the frames and glass are in good order, resealing the joints is often all that is needed. Problems with the glass or gaskets are for a window company, and we will say so. Around Rushden, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why us?
- Colour picked to suit the job
- More than 20 years in sealant work
- Neat joints and a tidy finish
- ARBOMaster approved applicator
