Sand Mastic in Dibden Purlieu
Sand mastic in Dibden Purlieu from a team with over 20 years’ experience. 180+ five-star Google reviews and a 4.9 rating.
- Modern sealant on a period surround
- Crumbling sand mastic round a window
- Tired mastic found when preparing windows for paint
What happens if it’s left?
Not every filler suits an old window surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Homes in smaller places like Dibden Purlieu 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.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

How we handle sand mastic in Dibden Purlieu
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. If you have weathered mastic on the most exposed windows and wind and rain getting in round a sash window, we can help, whatever the surface.
Many houses in smaller places like Dibden Purlieu have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows.
Our work is backed for twelve months, in Dibden Purlieu and everywhere else we cover.

Surface by surface
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
Sash and case windows
Sash windows are where we do most sand mastic work. We renew the mastic round each box.
Common problems we fix in Dibden Purlieu
Rain on the window surround works into any crack and loosens it further. Exposed elevations usually fail first.
People generally contact us after spotting one of these:
- Draughty sash windows at the surround
- Cracked mastic round a front door frame
- Mastic worn away on windows facing the weather
- Mastic dropping out of the joint
In the older streets around St. Andrew's Church and Centre, the joint between an old wall and a newer frame is normally the first place rain gets in.

What affects the cost of sand mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The product the joint needs
- Mould in or behind the old joints
- The number and length of the joints
- The number of rooms or windows
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

How the visit works
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours per window, depending on the condition of the joints, depending on the size of the job. Parking around Dibden Purlieu is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height
- Let us know about parking restrictions
Ask for a quote
It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you are ready, phone 0345 464 0079 or drop us an email.
Advice
Dibden Purlieu homes and the weather
Dibden Purlieu is close to 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 older windows and doors, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Wildground Infant School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Southampton Town Quay station? Then any sash windows need sound mastic to keep draughts and rain out.

DIY sealant or a professional job?
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.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Dibden Purlieu questions
Is Dibden Purlieu within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Southampton Town Quay station. Can you help?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
What does sand mastic cost?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or drop us an email with a short description of the job.
Can you quote for more than one area?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Is it possible to take out silicone and use sand mastic instead?
Yes, we do this often. The old silicone has to come out completely so the mastic beds in well.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
How long does the job take?
That depends on the amount of work, but as a guide it takes a few hours per window, depending on the condition of the joints. We’ll give you a better idea when we quote.
