Lowford Window Mastic
We cover Lowford for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly.
- Mastic that is falling out in pieces
- Draughty joints inside around the window
- Damp patches on the reveal after heavy rain
How we handle window mastic in Lowford
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. Common call-outs are for white mastic on grey or black frames and old mastic that has gone black or come away, across timber windows & doors, patio & French doors and window sills.
In a smaller place like Lowford, some walls face open ground and catch the full force of the weather. The mastic around frames on those walls tends to age faster.
There’s a 12-month guarantee on every job, large or small.

When it is not the sealant
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Faulty window hardware
- A failed sealed unit that has misted up
- A door that needs adjusting, rehanging or new seals
If you are not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer.

What we are called out for in Lowford
Mastic ages in the weather. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Any of these means the joints need attention:
- Gaps where the sill meets the wall
- Damp patches on the reveal after heavy rain
- White mastic on grey or black frames
- Cracked internal joints between frame and plaster
If you live in an older home near St Paul’s Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

FAQs for Lowford
I let a flat near Bursledon station. Can you help?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Does living near the coast affect window mastic in Lowford?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
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.

Should I try it myself first?
A careful DIYer can reseal a simple joint, 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.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What window mastic looks like in Lowford
Lowford is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Historic houses like Medieval Merchant's House (about 3.7 miles west) are a reminder that the area around Lowford has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Letting a property close to Bursledon station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For site and facilities teams at buildings such as Bursledon Church of England Infant School, larger buildings have plenty of frames, and the mastic around each one ages.

Surface by surface
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We’ll tell you which suits your home.
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it.
Aftercare tips
To keep the joints looking good and working properly:
- Keep solvents and bleach off the sealant
- Keep jet washers away from the mastic
- Keep paint off silicone joints
- Clean frames with a soft cloth and soapy water
Most silicone sealants won’t take paint, so mention any painting plans before work begins. There are paintable sealants for joints that need it.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a few frames, or a day or more for a whole house. For a job in Lowford, 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 go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Mention any parking rules near the property
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we are working on
