How the job changes by surface
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. If we find rot, we’ll tell you before going ahead, as that is a job for a joiner.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match keeps the clean look.
Window mastic in Strood
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that can’t move properly, so deep gaps get backing rod first. The sealant then grips the two sides it should. Typical jobs include cracked internal joints between frame and plaster and water coming in at the bottom corners of a door, across composite doors, aluminium frames and window sills.
Walls in Strood that face the prevailing wind take the most weather, and that is usually where the sealant gives up first. It’s worth looking at every frame, not just the one that leaks.
There’s a 12-month guarantee on every job, whatever its size.

How the visit works
The work is kept neat and contained to the joints we’re treating. Expect the work to take anything from an hour or two to a full day, depending on how many frames there are. In Strood, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Keep children and pets away from the work area
- Let us know about parking restrictions
- Tell us about any previous sealing or DIY attempts

Honest limits
We will not take on work that won’t last, so these are the limits:
- Faulty window hardware
- A frame that has rotted at the joint
- Worn gaskets, brush seals or a door that has dropped
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.
Joints and surfaces we work on
- Composite doors
- Aluminium frames
- Window sills
- uPVC windows
- Timber windows & doors
- Patio & French doors
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep paint off silicone joints
- Do not aim a pressure washer at the joints
- Keep drainage slots and sill grooves clear
- Ventilate rooms so frames don’t stay wet inside
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
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. Catching it early keeps the fix to a reseal.

Window mastic in Strood: local notes
With historic houses such as Temple Manor (about 0.5 miles south-east) nearby, there’s older building stock in the area around Strood as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Rented homes near Strood station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. If you live in an older home near St Francis' Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What affects the quote in Strood
The price is agreed before any work begins. It takes into account:
- The old material and how stubborn it is
- The product the joint needs
- Any mould that needs treating
- How many rooms, windows or areas are involved
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
Photos by email are helpful but not essential. Try to tell us:
- The rough size of the job
- The address or postcode of the job
- Access, such as stairs, a lift or height
- If someone has resealed it before
We quote each job on its own. Just phone 0345 464 0079 or email us with the details and send pictures if you have them.
When to call us in Strood
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. A sealant that cannot keep up eventually tears.
The most common problems we see are:
- Gaps left after new windows were fitted
- Old mastic that has gone black or come away
- Draughty joints inside around the window
- Rain getting in at the frame or under the sill
Managing a site like Elaine Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
What to look for in a quote
- How the joint is cleaned and prepared
- What insurance they hold
- Who turns up on the day
- The length of the guarantee
