Different surfaces, different methods
Brick and stone facades
Stone can absorb plasticisers from the wrong sealant. We use a product suitable for the stone where the specification names one.
Precast concrete panels
Precast panel joints have to absorb thermal and structural movement. We use a sealant with the right movement capability, set over backing rod.
About our facade sealing in Sheerness
Most facade joint failures trace back to the joint, not just the sealant. The width has to suit the expected movement and the sealant’s movement capability, while rod fixes the depth and stops the bead sticking to the rear with the ratio the sealant maker recommends, often around 2:1. Most enquiries involve discoloured or dirty facade joints and perimeter joints where frames meet the structure, across perimeter joints where frames meet the structure, stone and brick facade joints and window and door perimeters. Looking for mastic applicators who cover Sheerness? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Conversions around smaller places like Sheerness often join new frames to old masonry or timber, which leaves joints between old walls and new frames that need a sealant able to take the movement.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

After the work
A few simple habits keep the new joints working:
- Check the asbestos register before old mastic is disturbed
- Brief window cleaners about newly sealed joints
- Inspect facade joints on a regular cycle
- Never let anyone seal over old sealant
Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it, and work stops until it’s tested if it’s suspected.
Why it’s worth doing now in Sheerness
Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Questions we’re asked in Sheerness
Can being near the sea in Sheerness affect the sealant we need?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.
Is Sheerness off your patch?
No. Places such as Sheerness are covered as much as the big towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Will you check whether the sealant is causing the leak?
Yes. Photos help, and you can call the office on 01277 525 020 or email a schedule or drawings to arrange a visit. Many frame leaks are sealant failures, though not all, and we’ll tell you which.
Do you offer coloured sealant?
That depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Do you seal facades in winter?
We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Frost and condensation on glass and steel are common on winter mornings, and we build that into the programme.

What else we do in Sheerness
On site: what to expect
Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you. What matters most for a job in Sheerness is a clear list of what needs doing. A fixed quote follows.
- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
Preparing the site
- Arrange parking or a loading space
- Move anything stored against the joints
- Point out any areas we must not close

Sites and facades in and around Sheerness
Sheerness lies within about 1 mile of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. The area within 2 miles of Sheerness holds a number of hotels. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.
Extensions at sites like Sheppey Community Hospital, 2.1 miles south-east of Sheerness, usually sit beside working departments, and the mastic follows strict access rules. Projects at schools like Rose Street Primary School work to term dates, so mastic is programmed tightly. For contractors at a college like Sheppey College (less than half a mile north of Sheerness), perimeters and internal sealant are timed for the holidays.
