About our mastic sealing in Lower Upnor
On a residential block, the work happens around people’s lives. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Communal entrances and stairs stay usable while we work. Most enquiries involve complaints coming in block by block and water getting in round frames after rain, on shopfronts below residential blocks, window and door perimeters on blocks and communal entrances and stairwells. A specialist sealant contractor works differently from a general builder: on jobs in Lower Upnor, preparation and product choice get the time they need.
Rural conversions near places like Lower Upnor often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.
We stand by our work: 12 months, guaranteed. That covers our preparation and application.

Our process
At the end of each section, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. Jobs in and around smaller places like Lower Upnor are usually planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Preparing the site
- Clear stock, furniture or equipment away from the joints
- Warn occupants and staff about the work
- Tell us which areas need to stay in use

When to call us in Lower Upnor
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, with joints near the floor and around doors suffering most. Cleaning products add to the wear.
If one of these sounds familiar, it’s time for a closer look:
- Complaints coming in block by block
- Water getting in round frames after rain
- Brittle perimeter mastic across a building
- Estate-wide sealant that is simply worn out
For owners of several units at places like Pier Road Industrial Estate, 1.6 miles to the south-east of Lower Upnor, one programme can deal with frame and external mastic across the lot.
Questions to ask before you book
- Is the sealant right for the movement and the substrate?

Questions we’re asked in Lower Upnor
Can you quote for a block close to Strood station?
Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Will you take on work at estates like Pier Road Industrial Estate, close to Lower Upnor?
Yes. Estates, retail parks and business parks around Lower Upnor, Pier Road Industrial Estate among them, are all within reach. To start, just ring 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
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, so we will confirm the curing time on the day.
How do you reach windows on upper floors?
Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned and we’ll confirm the approach in the quote.
Is asbestos a concern with old mastic?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
Site staff or a sealant specialist?
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
What sealant work can’t fix
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Leaks from above rather than through a joint
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Misted or failed double-glazed units
If in doubt, speak to us on 01277 525 020 or use the quote form and we’ll say what we think.

Why deal with it now?
Reacting to every complaint means sending someone out block by block. A planned programme treats each building once, under a single quote and a single programme. Halls, stores and units around places like Lower Upnor may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
A quote for mastic joints depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.
