Lidsing: your questions answered
Can you help a landlord with a rental near Rainham (Kent) station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Do you cover Lidsing for window mastic?
Yes, Lidsing is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
Can you seal the gap between the frame and the plaster indoors?

We keep the work tidy. Nearby surfaces are protected.
How many windows can you do in a day?

When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you.
Window mastic in Lidsing
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through and quietens the whistle on windy days. If the draught is through the window seals instead, we’ll tell you. If you have a bead that doesn’t match the frame and whistling draughts around closed windows, we can put it right.
Around Lidsing, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Frames and glazing around Lidsing
Historic houses like Restoration House (about 4.7 miles north-west) are a reminder that the area around Lidsing has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of St Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Rainham (Kent) station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you look after a building such as Swingate Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
Lidsing is about 2 miles south-east of Chatham, in Medway. Lidsing gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee.

Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
We also work for property managers and facilities teams. Several sites can go on one quote.
Different surfaces, different methods
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour suits the frame.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What affects the cost of window mastic
Your quote is based on your job. We take into account:
- Whether the work is at height
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
- The size of the job
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

What else we do in Lidsing
How it works
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from an hour or two to a full day, depending on how many frames there are. In a small place like Lidsing, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Preparing for the visit
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children
Getting a quote

Related advice
Why deal with it now?
A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. The old mastic has to come out. Around Lidsing, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep drainage slots and sill grooves clear
- Walk round the house once a year and look at the joints
- Wash the frames with mild soapy water
- Paint up to the joint, not over it
Check the drainage slots in the frames are not blocked, so water can run away instead of sitting against the joint.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
