Mastic sealing in Sprat's Down
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
How the quote is worked out
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Distance, for remote addresses
- Induction, permit and paperwork requirements
- Any access equipment needed
- Backing rod, priming and other preparation
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.
Before you send an enquiry
There’s no need for a formal survey. A few details are enough to get going:
- How the joints are reached, and at what height
- Asbestos survey details if the building is older
- Your programme or deadline
- The site address and postcode
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
Mastic sealing in Sprat's Down, done properly
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. We work on window and door perimeters on blocks, external wall and movement joints and communal entrances and stairwells, and the failures we are asked to look at most are cracked, hardened mastic round windows on a block and estate-wide sealant that is simply worn out. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Sprat's Down, preparation and product choice get the time they need.
Owners and agents with buildings around smaller places such as Sprat's Down tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

What the job involves on each surface
Commercial and mixed-use buildings
Commercial buildings have mastic at shopfronts, entrances and external joints. We work across portfolios on a planned basis.
External movement joints
Brickwork, blockwork and panel joints let a building move. Once that sealant goes, rain can reach the wall.
Owners, agents and contractors
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sprat's Down can form part of a wider programme across Hampshire.
For owners and agents in Sprat's Down
Sprat's Down sits close to the coast, within about 1 mile. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first, and they deserve more regular inspection. Sprat's Down sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.
Historic properties like Beaulieu Palace House (to the west of Sprat's Down) show the age of some local stock, where frame mastic must suit soft brick or stone. Landlords with units on estates such as Glenmore Business Park (2.9 miles north-west of Sprat's Down) can bring frame, door and external mastic across several units into one programme.
Sprat's Down is about 4 miles north of Cowes, in Hampshire. Anywhere in SO45, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

Local landmarks in Sprat's Down

Site staff or a sealant specialist?
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Do you need mastic sealing in Sprat's Down?
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, and low-level joints get damaged. Cleaning products add to the wear.
Clients normally get in touch after noticing one or more of the following:
- Complaints coming in block by block
- Mastic failing across several blocks on an estate
- Draughts at frames across a block
- Water getting in round frames after rain
Schools and community buildings such as Fawley Infant School need frame and external mastic kept sound like any building.
Questions to ask before you book
- How joint depth will be controlled
- Will RAMS and insurance details be available?

What else we do in Sprat's Down
Your questions answered
Is a smaller place like Sprat's Down outside your area?
Not at all. Sprat's Down is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Will you take on a block within reach of Hamble station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.
How long does a typical visit take?
It depends on the scope, though a typical visit usually takes one or more days per building, depending on the joint lengths and the access. For bigger or phased jobs, we will set out a timescale with the quote.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Do you check for asbestos in old sealant?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
How a job runs
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Rural sites near Sprat's Down may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
