Why it’s worth doing now in Furzeley Corner
Choosing the product is half the job. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Around Furzeley Corner, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why Furzeley Corner clients choose us
- Sealant colour chosen to suit
- Every job guaranteed for a year
- Homes, businesses and hotels
- More than 20 years in sealant work

Window mastic in Furzeley Corner
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. We are often asked to deal with water coming in at the bottom corners of a door and black, perished sealant on frames, across uPVC windows, patio & French doors and window sills.
Around Furzeley Corner, 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.

FAQs for Furzeley Corner
I let a flat near Cosham station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Does living near the coast affect window mastic in Furzeley Corner?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Is the work guaranteed?
Yes. Each job is covered for 12 months, inside or out.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Do you have sealant for grey or black windows?
Yes, in most cases. Tell us the frame colour when you get in touch and we will match it as closely as we can.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Do you cover Furzeley Corner?
Yes. We work in Furzeley Corner and the rest of Hampshire. To book, phone 0345 464 0079 or send us an email.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
What window mastic looks like in Furzeley Corner
Furzeley Corner is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around window and door frames, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Cosham station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Rotten timber, which needs a joiner first
- A sash or casement that will not close properly
If you are not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.
Surfaces we seal
- Composite doors
- Timber windows & doors
- Window sills
- Patio & French doors
- uPVC windows
- Aluminium frames
When to call us in Furzeley Corner
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. If the sealant can’t stretch, it splits.
It’s worth asking for a quote if you see:
- Untidy mastic left by window fitters
- Whistling draughts around closed windows
- Damp patches on the reveal after heavy rain
- Cracked sealant at the sill ends
For site and facilities teams at buildings such as Denmead Junior School, the mastic around its windows and doors needs looking after like any other building’s.

DIY sealant or a professional job?
If you do try it yourself, take your time over the 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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

What else we do in Furzeley Corner
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Keep jet washers away from the mastic
- Paint up to the joint, not over it
- Clear any debris from frame drain holes
- Wash the frames with mild soapy water
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
