Window mastic for homes and businesses in Purfleet-on-Thames
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. Typical jobs include a bead that doesn’t match the frame and black, perished sealant on frames, on uPVC windows, composite doors and timber windows & doors.
In a smaller place like Purfleet-on-Thames, some walls face open ground and catch the full force of the weather. The mastic around frames on those walls tends to age faster.

Window mastic in Purfleet-on-Thames: local notes
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Rainham Hall (about 3.1 miles north-west) are a reminder that the area around Purfleet-on-Thames has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For an older house near a landmark such as St Stephen's Church, the joint between an old wall and a newer frame is usually the first place rain gets in. Schools such as Purfleet Primary Academy are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Purfleet-on-Thames: your questions answered
Do you work for landlords with property near Purfleet station?
Yes. We work for landlords and agents as well as homeowners. You can ring 0345 464 0079 or email us with the details for a clear quote.
Is Purfleet-on-Thames in your area for window mastic?
Yes. Our work covers London and the South East, and Purfleet-on-Thames is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.
Do you have insurance?
Yes. We are fully insured, and we have been doing sealant work for more than 20 years.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Can resealing stop a draught around my window?
In many cases. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
When it isn’t the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A frame that has rotted at the joint
- Broken hinges, locks or handles
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.
What we seal
- Composite doors
- uPVC windows
- Aluminium frames
- Window sills
- Patio & French doors
- Timber windows & doors
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Make sure the drainage slots aren’t blocked
- Keep paint and stain on wooden frames in good order
- Keep paint off silicone joints
- Wipe condensation off the frames
Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How the visit works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take most of a day for a typical house, less for a few frames. For a job in Purfleet-on-Thames, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Preparing for the visit
- Keep children and pets away from the work area
- Mention if the joints have been sealed before
- Mention any parking rules near the property

For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Common problems we fix in Purfleet-on-Thames
Mastic ages in the weather. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
Keep an eye out for these signs:
- Draughty joints inside around the window
- Gaps left after new windows were fitted
- Mastic that is falling out in pieces
- Cold air getting in at the frame edge
Letting a property close to Purfleet station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
