Mastic sealing in Sharnal Street
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Doing it in-house
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
About our mastic sealing in Sharnal Street
Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Entrances and stairwells are kept in use while we work. Site teams most often ask us about patchy repairs in mismatched sealant and damp patches beside frames, across balcony and threshold joints, external wall and movement joints and communal kitchens and washrooms. For commercial sealant work in Sharnal Street, you deal with one contact from quote to sign-off, whether it’s one building or several.
Owners and agents with buildings around smaller places such as Sharnal Street tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or send photos by email and we will come back to it.

Block-wide mastic in Sharnal Street
Sharnal Street sits close to the coast, within about 2 miles. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first; plan inspections around that. Sharnal Street is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.
For agents with blocks near Gillingham (Kent) station, which lies south of Sharnal Street, a block-wide mastic programme deals with frames, balconies and entrances in one go. If your remit includes a building such as High Halstow Primary Academy, frame and door mastic can be programmed for the holidays. Older buildings near Sharnal Street, from historic houses such as Restoration House (4.9 miles south-west of Sharnal Street) to more modest stock, need compatible products when frames are resealed.
Sharnal Street is about 5 miles north of Gillingham, in Medway. Our applicators travel to Sharnal Street for work on mastic joints, handled exactly as we handle every other area. Sharnal Street is one of 54 places in Medway on our list for mastic joints. We also cover London, around 29 miles from Sharnal Street.

Common questions from Sharnal Street clients
Does the sea air around Sharnal Street change the choice of sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Is Sharnal Street off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
What paperwork can you provide?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
Can you quote from photos?
It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs usually get a visit.
How many days will you need on site?
It depends on the scope, but the work normally takes one or more days per building, depending on the joint lengths and the access. Larger or phased jobs take longer, and we will give you a timescale with the quote.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
Commercial clients in Sharnal Street
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Why deal with it now?
Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. Older rural buildings around Sharnal Street move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Access can matter as much as the joints themselves: 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 you get with us
- Colour options checked against the specified product
- Fully insured, including public liability cover
- A range of standard colours, depending on the product
- Old sealant cut out, never sealed over

Looking after the joints
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Mention RAMS, insurance or CSCS requirements up front
- Check the asbestos register before any old mastic is disturbed
- Log resealing dates block by block
- Prioritise elevations facing the weather
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing.

What we can’t put right
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Misted or failed double-glazed units
- Masonry that has broken away beside the joint
Not sure which it is? You can phone 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.
