Poulner Window Mastic
Mastic around window and door frames, sills and patio doors for homes and businesses in Poulner and across Hampshire. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Cracked or shrunken mastic around the frame
- Black, perished sealant on frames
- A bead that does not match the frame
How it works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes anything from an hour or two to a full day, depending on how many frames there are. For a job in Poulner, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- 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.

How we handle window mastic in Poulner
The new joint does not have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. We work on patio & French doors, composite doors and window sills, and people most often call us about damp patches on the reveal after heavy rain and whistling draughts around closed windows.
Houses in smaller places like Poulner can stand more in the open than those in a built-up town. That’s hard on the mastic around frames and sills.
There’s a 12-month guarantee on every job, large or small.

Common questions in Poulner
Do you cover Poulner for window mastic?
Yes. Our work covers London and the South East, and Poulner is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.
Is there a guarantee on window mastic in Poulner?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Can I add another job to the visit?
Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Will new mastic stop draughts?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Can you match the sealant to my frames?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Poulner homes and the weather
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. With historic houses such as Avon Tyrrell House (about 3.8 miles south) nearby, there’s older building stock in the area around Poulner as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Poulner Infant School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What else we do in Poulner
What happens if it’s left?
If you are painting or rendering, reseal at the same time. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Homes in smaller places like Poulner can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Do not paint over the silicone
- Avoid blasting the frames with a pressure washer
- Make sure the drainage slots are not blocked
- Clean frames with a soft cloth and soapy water
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
When to call us in Poulner
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar never bonded as it should, and it lets go sooner than it should.
Look out for these signs:
- Cracked internal joints between frame and plaster
- Damp patches on the reveal after heavy rain
- Untidy mastic left by window fitters
- Mastic that has split away from the wall
Homes close to St John the Baptist include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
