Lower Hardres Window Mastic
Window and door frames in Lower Hardres need attention? We cut out the old, prepare the joints and apply the right sealant.
- Black, perished sealant on frames
- Draughty joints inside around the window
- Untidy mastic left by window fitters
Window mastic in Lower Hardres, done properly
Homes in Lower Hardres have every kind of window: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. If you have old mastic that has gone black or come away and untidy mastic left by window fitters, we can put it right.
Somewhere as small as Lower Hardres, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Each job carries a 12-month guarantee, whatever its size.

What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes most of a day for a typical house, less for a few frames. In a small place like Lower Hardres, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any previous sealing or DIY attempts

Landlord and commercial work in Lower Hardres
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.
What the job involves on each surface
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.
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.
What sealant work can’t fix
Before booking, it’s worth knowing the limits too:
- Damp coming through the wall itself rather than the frame joint
- Faulty window hardware
- A failed sealed unit that has misted up
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.
What we seal
- Window sills
- uPVC windows

Can you help a landlord with a rental near Canterbury East station?

Do you do commercial work?

How long does it take to reseal the windows on a house?
A few frames take a few hours, while a whole house takes longer. You will get a timescale with the quote.
Does the work come with a guarantee?
Yes. Every job comes with our 12-month guarantee, and we are ARBOMaster approved applicators.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
Aftercare tips
A little care helps the new joints last. We recommend:
- Use gentle cleaners on frames and sealant
- Make sure the drainage slots are not blocked
- Avoid blasting the frames with a pressure washer
- Keep timber frames painted
Silicone cannot normally be painted, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
What happens if it’s left?
Failed mastic is not a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that is needed. Problems with the glass or gaskets are for a window company, and we will say so. In a small place like Lower Hardres, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.

- Fully insured
- We leave the area clean and tidy
