How we handle construction mastic in Rowner
Most of the packages we price run well beyond frames: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. Splitting those between trades often leaves gaps in responsibility and gives you a consistent finish across the job. We work on sanitary and kitchen joints, brick and block movement joints and floor and skirting junctions, and the usual reasons a site gets in touch are missed perimeter joints on a new elevation and failed sealant in an existing building being refurbished. Looking for mastic applicators who cover Rowner? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
On a small site around Rowner, the mastic is best done in the fewest visits we can manage. Tell us when scaffold comes down and when decoration finishes, and we’ll plan around those stages.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

What affects the price in Rowner
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Quantities, in metres or numbers
- Phasing around occupants
- Location, for remote and island sites
- How accessible the joints are
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.
Sending details for a quote
Whether it’s one area or a whole building, the same details help:
- What the building is and how it’s used
- Clear photos of the problem areas
- Access details, including height
- The asbestos register, for older buildings
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Contractors’ notes for Rowner
The sea is no more than about 2 miles from Rowner. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so we check the specified product suits the exposure before the first bead. Rowner is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack.
When a college such as St Vincent College, 2.2 miles to the south-east of Rowner, builds or refurbishes, the mastic package typically has to fit around students and staff. For contractors at a school such as Bridgemary School, sealing has to be finished before term starts. Extensions at sites like Gosport War Memorial Hospital, 2.3 miles to the south-east of Rowner, usually sit beside working departments, and the mastic follows strict access rules.
Rowner is about 2 miles north-west of Gosport, in Hampshire. We cover Rowner and the rest of Hampshire, with the same fixed quotes and 12-month guarantee as everywhere else. Across Hampshire, 723 places are covered, Rowner among them.

Your questions answered
Can you take on a job at a hospital such as Gosport War Memorial Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Our building in Rowner is near the coast: does that change the sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.
Do you take on mastic snagging only?
Yes. Damaged, missed or untidy joints are stripped and done again properly.
How much does the work cost?
It depends on the job: quantities, access, the product and any phasing. Call for a quote and we will price it properly.
What happens if the weather stops external sealing?
Outside, the joint has to be dry and the temperature within the product’s limits. Frosty or damp mornings can hold up external sealing, so internal areas are often done on those days.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Can the sealant be colour-matched?
It depends on the product specified. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
Building owners, agents and FMs in Rowner
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.
Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Doing it in-house
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Keeping the joints sound
A few simple habits keep the new joints working:
- Check frame gaps are within the sealant’s range before sealing
- Plan external elevations with the weather in mind
- Record the products used in the O&M file
- Ask cleaners to use soft cloths around fresh sealant
If a joint is damaged after sealing, flag it early. Snags can be picked up in a planned close-out visit, priced as part of the package or separately.
A missed perimeter seal on one window can wet the reveal and the plaster inside. That usually means redoing finishes in a completed area, and a delay to handover. Checking perimeters before internal finishes go on avoids it.
Why it’s worth doing now in Rowner
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. Sound frames often need only a new perimeter seal. If the frame is life-expired, we will tell you. For buildings in places like Rowner, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
