Window mastic for homes and businesses in Hiltingbury
Around Hiltingbury we seal all kinds of frames: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. If you are dealing with draughts coming in around windows and doors and cracked internal joints between frame and plaster, we can put it right.
Houses in smaller places like Hiltingbury can stand more in the open than those in a built-up town. The mastic around frames on those walls tends to age faster.
We stand behind the work with a one-year guarantee.

Are you fully insured?

How long will my window job take?
That depends on the number of frames, how they’re reached and the state of the old mastic. We’ll tell you how long your job needs when we quote.
How long should I leave it?
It depends on the product. We tell you how long to leave it before we go.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Can I paint over the new sealant?
It depends on the sealant. Silicone isn’t paintable, but some hybrid sealants are. Tell us if you are decorating and we will choose accordingly.
Do you work on first-floor windows?
Yes, in most cases. Access is planned before any work starts.
For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly 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 give you a quote.
When to call us in Hiltingbury
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Any of these means the joints need attention:
- Damp patches on the reveal after heavy rain
- Cold air getting in at the frame edge
- Mastic that has split away from the wall
- Rushed sealant from a window installation
If you look after a building such as Hiltingbury Junior School, the mastic around its windows and doors needs looking after like any other building’s.
Before you book anyone
- How the surfaces are prepared before sealing
- How long the guarantee is
- What happens if the job turns out different
- Which colour the sealant will be
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep drainage slots and sill grooves clear
- Keep timber frames painted
- Avoid harsh chemicals near the mastic
- Avoid blasting the frames with a pressure washer
Most silicone sealants won’t take paint, so mention any painting plans before we start. There are paintable sealants for joints that need it.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.
Surface by surface
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
Composite doors
A composite door generally sits in a plastic outer frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.

Window mastic in Hiltingbury: local notes
With historic houses such as South Stoneham House (about 4.3 miles south) nearby, there’s older building stock in the area around Hiltingbury as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Chandlers Ford station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Homes close to St. Martin in the Woods 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?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from an hour or two to a full day, depending on how many frames there are and we leave things clean and tidy. For a job in Hiltingbury, 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.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Getting ready for the visit
- Let us know about parking restrictions
- Clear items away from the joints we are working on
- For indoor joints, keep the area dry beforehand if you can
