Window & door mastic in Finkley Down, Hampshire
Our applicators work in Finkley Down on mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Sealant in the wrong colour for the frame
- Damp patches on the reveal after heavy rain
- Gaps between the frame and the inside reveal
What we cannot put right

- Condensation trapped between the panes
- Damp problems in the wall away from the window
- A door that needs adjusting, rehanging or new seals
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before booking.

Window mastic in Finkley Down
Around Finkley Down we seal all kinds of frames: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on timber windows & doors, composite doors and window sills, and people most often call us about a bead that doesn’t match the frame and damp patches on the reveal after heavy rain.
Mastic can only go onto a dry, clean joint, so window work in Finkley Down is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Wash the frames with mild soapy water
- Look round the frames every year or so
- Keep solvents and bleach off the sealant
- Make sure the drainage slots are not blocked
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Signs you need window mastic in Finkley Down
Sun, frost and rain wear sealant out. Sunlight dries the surface out, until it loses its stretch and starts to crack.
The problems people generally mention when they call include:
- Gaps where the sill meets the wall
- Old mastic that has gone black or come away
- Gaps left after new windows were fitted
- White mastic on grey or black frames
Rented homes near Andover station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in.
How long should I leave it?
Cure times vary by product and the temperature. Before we leave, we will tell you the cure time.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

Silicone generally will not take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Are you fully insured?

Can I do it myself?

How the visit works
Before we leave, we go over the finished joints with you. The work normally takes most of a day for a typical house, less for a few frames, depending on how much there is to do. Somewhere as small as Finkley Down, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- 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
- On commercial sites, let us know about site rules
- Clear the area around the work
- Mention if the joints have been sealed before

Why act early in Finkley Down
The work is quick compared with the damage it prevents: the visit takes a few hours for a few frames, or a day or more for a whole house. Wait for damp to appear and there may be plaster and decorating to sort out too. In a small place like Finkley Down, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Why us?
- Trusted Arbo and Everbuild sealants
- A sealant colour to suit the surroundings
- Domestic, commercial and hotel work
- We’re fully insured
Different surfaces, different methods
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
Patio & French doors
Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
