Common problems we fix in Lordswood
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
Most people get in touch when they notice one of these:
- Old mastic that has gone black or come away
- Cracked internal joints between frame and plaster
- Mastic that has split away from the wall
- Rushed sealant from a window installation
Letting a property close to Millbrook (Hants) station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Window mastic in Lordswood, done properly
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. If you’re dealing with rain getting in at the frame or under the sill and mastic that’s falling out in pieces, we can help, whatever the surface.
Many houses in smaller places like Lordswood have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Landlord and commercial work in Lordswood
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Your questions about window mastic in Lordswood
Do you work for landlords with property near Millbrook (Hants) station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Does the coastal weather in Lordswood affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Is the work guaranteed?
Yes, for 12 months. A yearly look at the joints helps them last.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Do you have sealant for grey or black windows?
Yes. White, brown, anthracite grey, black and clear sealants are all available.
Can new window sealant be painted?
Not usually, if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.

What happens on the day
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a few frames, or a day or more for a whole house in most cases. A visit to Lordswood is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Mention any parking rules near the property
- Mention if the joints have been sealed before
- Tell us about access, such as stairs, a lift or high-level joints

Looking after it afterwards
So the new joints stay in good condition:
- Ventilate rooms so frames don’t stay wet inside
- Keep paint and stain on wooden frames in good order
- Clear any debris from frame drain holes
- Don’t aim a pressure washer at the joints
Silicone cannot usually be painted, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
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.
What the job involves on each surface
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We’ll tell you which suits your home.
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the new bead is laid against the frame and the wall and tooled smooth.
How we quote for window mastic
There’s no set price list. The quote depends on:
- The number and length of the joints
- Which sealant suits the joint
- Any working-time requirements on site
- Whether the work is at height
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.
What we need to know
What to tell us when you ask for a quote:
- Whether it has been sealed before
- A few pictures by email, if you can
- The address or postcode of the job
- The rough size of the job
Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job.
Window mastic in Lordswood: local notes
Lordswood is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Oakwood Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. Homes close to Lord's Hill Church include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.
