FAQs for Watermead
Can you help a landlord with a rental near Aylesbury station?
Yes. We work for landlords and letting agents as well as homeowners. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Is Watermead in your area for window mastic?
Yes, Watermead is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will send you a clear quote.
Can new window sealant be painted?
That depends on the product. Silicone isn’t paintable, but some hybrid sealants are. Tell us if you are decorating and we will choose accordingly.
Do you have sealant for grey or black windows?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Will there be a smell?
Some sealants have a smell while they cure. Ventilation helps.
Will resealing my frames help with draughts?
It will if the frame joint is the problem. We check where the draught is before any work starts.
Do you seal inside as well as outside?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
About our window mastic in Watermead
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through. If the draught is through the window seals instead, we will tell you. Typical jobs include sealant in the wrong colour for the frame and leaking joints at the ends of sills, across window sills, patio & French doors and uPVC windows.
In smaller places like Watermead, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
You are covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or email us.

Different surfaces, different methods
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match keeps the clean look.
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Damp coming through the wall itself rather than the frame joint
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A frame that has rotted at the joint
If in doubt, ring 0345 464 0079 or email us and we will say what we think before booking.

Watermead homes and the weather
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you let a flat or house near Aylesbury station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For site and facilities teams at buildings such as St Louis Catholic Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Keep jet washers away from the mastic
- Walk round the house once a year and look at the joints
- Repaint timber before it’s bare
- Clean frames with a soft cloth and soapy water
Silicone can’t normally be painted, so if you’re planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for a handful of frames, longer for a whole house. In a smaller place like Watermead, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- 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.
- 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
- Plan for the work area to be out of bounds to pets and children
- Clear the area around the work
- Mention any leaks or damp you’ve noticed

Advice
Do you need window mastic in Watermead?
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
Signs it’s time to call us include:
- Black, perished sealant on frames
- Untidy mastic left by window fitters
- Cracked internal joints between frame and plaster
- Leaking joints at the ends of sills
If you live in an older home near Church of St James, the joint between an old wall and a newer frame is generally the first place rain gets in.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Landlord and commercial work in Watermead
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
