Mastic sealing for Berwick sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Should maintenance staff do it?
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 easy to get wrong without experience.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Mastic sealing in Berwick
On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Communal entrances and stairs stay usable throughout. We work on balcony and threshold joints, communal kitchens and washrooms and communal entrances and stairwells, and the failures we’re asked to look at most are water getting in round frames after rain and window mastic that has split and shrunk. A specialist sealant contractor works differently from a general builder: on jobs in Berwick, preparation and product choice get the time they need.
Owners and agents with buildings around smaller places such as Berwick 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, call 01277 525 020 or email a schedule or drawings and we will come back to it.

When it isn’t the sealant
Being straight saves everyone time. New sealant won’t cure:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Water coming in from the roof or rainwater goods
If you’re 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.

Different surfaces, different methods
Commercial and mixed-use buildings
Mixed-use buildings combine shops below with flats or offices above, so phasing has to suit both. Tell us your site hours and access windows and we will plan around them.
Planned maintenance
We can work into your cyclical maintenance plan on a timetable you set.
Berwick: questions and answers
Do you work in occupied care homes around Berwick?
Yes. Care settings are planned area by area, at times agreed with the home. We follow the home’s own procedures throughout.
Do you work for managing agents with blocks near Westenhanger 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’ll quote and plan to suit.
Is mastic sealing guaranteed?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
Do you work for managing agents and housing associations?
We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Does the weather affect the work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Do you check for asbestos in old sealant?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
Work for main contractors and building owners
If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes one or more days per building, depending on the joint lengths and the access, and our waste is bagged and taken away as we go. Jobs in and around smaller places like Berwick are typically planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- We inspect each building and record the joints that have failed.
- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.
- Old mastic is removed and the joint faces prepared.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
What we need from you
- Confirm the product named in the specification
- Let building users know which areas are affected
- Agree which areas must stay open
Request a quote
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
Advice
What affects the price in Berwick
There’s no standard rate for sealant work, because every site is different. What we look at:
- Working within restricted access windows
- Removal of failed or old sealant
- Which sealant the job calls for
- Travel to remote or island sites
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.
Sending details for a quote
Good information means a firmer quote. When you get in touch, include:
- Your programme or deadline
- The product your specification calls for
- How the joints are reached, and at what height
- What the building is and how it’s used
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call the office on 01277 525 020 or email drawings and photos with what you know.

Looking after buildings in and around Berwick
Berwick is within about 2 miles of the coast. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints, and they deserve more regular inspection. Berwick has three care or nursing homes no more than 2 miles away. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings.
If you look after a block within reach of Westenhanger station (1 mile north of Berwick), frame and balcony mastic can be renewed on one programme. If you’re responsible for a building such as Church of St Stephen, frame and door mastic needs the same attention as any other property. Schools and community buildings such as Lympne Church of England Primary School need frame and external mastic kept sound like any building.
