How we handle construction mastic in Bridgemary
Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone. New and existing joints then get the same preparation. If you have missed perimeter joints on a new elevation and failed sealant in an existing building being refurbished, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Bridgemary, preparation and product choice get the time they need.
On a small site around Bridgemary, 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. It’s a plain promise: if our work fails within that year, we put it right.

Common problems we fix in Bridgemary
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We stick to the specified product, or put any alternative to you first.
What tends to prompt an enquiry:
- Different trades sealing to different standards
- Cracks opening in caulked internal joints
- External joints sealed in damp or cold conditions that are now failing
- Mastic snags holding up handover
Extensions at sites like Gosport War Memorial Hospital, 2.1 miles to the south-east of Bridgemary, normally sit beside working departments, and the mastic follows strict access rules.
Questions to ask before you book
- How the existing material will be dealt with
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- What the guarantee covers, and for how long
- How they handle RAMS and site documents
On site: what to expect
Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use. Work in places the size of Bridgemary is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- We seal plot by plot or floor by floor in line with the programme.
- Any frame gaps or issues outside our scope are flagged to the site team.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Before we start on site
- Share your working hours and any access restrictions
- Send asbestos survey details if the building is pre-2000
- Make sure the joints can be reached

Surface by surface
Fire-rated sealant where specified
Fire-rated sealant is one type of fire-stopping product. Other products are used for some services and gaps so we’ll flag where the detail needs something different. Record requirements are agreed with the quote.
Window and door perimeters
Inside, a paintable sealant or decorators’ caulk is used where the joint doesn’t move much. We follow what’s specified, and colour-matched products can be used where the frame is on show.
Honest limits
Being straight saves everyone time. Fresh joints won’t solve:
- Approving fire stopping as compliant
- Specifying the product where the designer hasn’t
- Joints damaged after sign-off by following trades
If you are not sure, just speak to us on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.
Surfaces we seal
- Floor and skirting junctions
- Internal decorators’ caulk
- Cladding and panel joints
- Window and door perimeters
- Sanitary and kitchen joints
- Brick and block movement joints
New build and refits around Bridgemary
The sea is no more than about 2 miles from Bridgemary. 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. Bridgemary 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, which is why external dates are agreed with the site manager.
When a school such as Rowner Junior is extended or refurbished, the mastic package is often squeezed into the holidays. Further education sites such as St Vincent College, 1.9 miles south-east of Bridgemary, are extended and refurbished from time to time, with mastic often programmed into the summer break.
Bridgemary is about 1 mile north-west of Gosport, in Hampshire. Bridgemary sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Hampshire coverage takes in 723 places, from busy centres to rural villages.
Anyone looking for construction mastic in PO13 and PO12 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee.

Just outside Bridgemary, we also work in Rowner (1 mile north-west), Peel Common (1 mile west), Elson (1 mile south-east), Crofton (1 mile west) and Gosport (1 mile south-east).

What affects the price in Bridgemary
Before we quote, we look at:
- Access and working height
- Whether old sealant has to be cut out first
- Specialist products, such as fire-rated or hygienic sealants
- The size and state of each joint
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
What we need to price the job
To price the job accurately, we need to understand the site. Useful things to include:
- The postcode of the building
- Anything awkward about access or site hours
- Photos of the joints, close up and from further back
- Any dates the work must fit around
Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, ring 01277 525 020 or email drawings and photos.

Bridgemary: questions and answers
Our building in Bridgemary is near the coast: does that change the sealant?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Is Bridgemary off your patch?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
What hours do you work?
Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you install fire-rated sealant as part of a package?
It can be part of the package where specified. Tell us what records you need and we’ll confirm with the quote.
How many days will you need on site?
That varies with the scale of the job, but the work usually takes as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Why it’s worth doing now in Bridgemary
A quick bead over a damaged joint can get an area past inspection, but it won’t last. New sealant laid on old or dirty sealant has nothing to bond to. Damaged joints are removed and resealed from clean faces. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
Pricing mastic packages depends on how many there are, their condition and the access. Call for a quote.
