Window mastic for homes and businesses in Stotfold Common
The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. We work on window sills, aluminium frames and composite doors, and the jobs we see most are rushed sealant from a window installation and sealant in the wrong colour for the frame.
Outdoor sealant needs dry, clean surfaces, so work on frames around Stotfold Common is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

Do you need window mastic in Stotfold Common?
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
Any of these means the joints need attention:
- Draughts coming in around windows and doors
- Untidy mastic left by window fitters
- Cracked sealant at the sill ends
- Sealant in the wrong colour for the frame
Homes close to Church of Saint Guthlac include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What we do, step by step
We bring everything the job needs with us. Once we’ve agreed what’s being done, we protect the area and start.

We bring what the job needs, so it can be finished in one trip 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.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.

Surface by surface
Window sills
Where a sill meets brick or render, the ends often crack first. A tight seal at each end keeps rain out of the wall.
Composite doors
Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We’ll tell you if that’s what we find.

Do you cover Stotfold Common for window mastic?
Yes, Stotfold Common is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Can resealing stop a draught around my window?
It will if the frame joint is the problem. We check where the draught is before work begins.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Can you do the inside joint as well?
Yes. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Wipe condensation off the frames
- Wash the frames with mild soapy water
- Don’t use solvent cleaners on the joint
- Keep paint and stain on wooden frames in good order
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
For landlords and businesses

Window mastic in Stotfold Common: local notes
Historic houses like Hinxworth Place (about 1.8 miles north-east) are a reminder that the area around Stotfold Common 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as St Mary's CofE Academy Stotfold, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Arlesey station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
