Heath Common Window Mastic
Mastic around window and door frames, sills and patio doors for homeowners, landlords and businesses in Heath Common. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Draughts coming in around windows and doors
- Rushed sealant from a window installation
- Cracked internal joints between frame and plaster
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Ventilate rooms so frames don’t stay wet inside
- Walk round the house once a year and look at the joints
- Make sure the drainage slots are not blocked
- Do not paint over the silicone
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
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.
Window mastic in Heath Common, done properly
If you can feel air around a shut window, the gap is often at the frame. 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 will tell you. If you have gaps left after new windows were fitted and black, perished sealant on frames, we can put it right.
In a village or hamlet like Heath Common, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Does someone need to be in?

Will you leave a mess?

What we do, step by step
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a few frames, or a day or more for a whole house. Somewhere like Heath Common needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
How to prepare
- Clear the area around the work
- Tell us about any water getting in
- Mention if the joints have been sealed before

Leave it or put it right?
If you are painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Around Heath Common, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

Different surfaces, different methods
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We will tell you which suits your home.
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.
Heath Common homes and the weather
With historic houses such as Parham House (about 3.1 miles west) nearby, there’s older building stock in the area around Heath Common 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Church of the Holy Sepulchre, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Thakeham Primary School, its window and door frames need their mastic kept sound, just like a home’s.

When to call us in Heath Common
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
The problems people normally mention when they call include:
- Rain getting in at the frame or under the sill
- Rushed sealant from a window installation
- Gaps between the frame and the inside reveal
- Mastic that’s falling out in pieces
Letting a property close to Pulborough station? Then renewing tired window mastic between tenants heads off draught and damp complaints.
