How we handle mastic sealing in Wareside
There isn’t one mastic for every joint on a building. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint. We will confirm the colours available for the specified product. Site teams most often ask us about the same joint failures repeated across a portfolio and brittle perimeter mastic across a building, across external wall and movement joints, shopfronts below residential blocks and window and door perimeters on blocks. A single leaking joint is often how a building in Wareside first comes to us: we look at the rest while we’re there and tell you what we find.
In and around smaller places like Wareside, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

On site: what to expect
At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. If others near Wareside need work, visits can be combined. A fixed quote is given before anything starts.
- Each block or building is walked and the failed joints recorded with the likely cause.
- 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.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Preparing the site
- Warn occupants and staff about the work
- Tell us what induction or permit system the site runs
- Move anything stored against the joints

Common questions from Wareside clients
Do you work for managing agents with blocks near Ware station?
Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.
Does your area include sites such as Home Farm Industrial Park, near Wareside?
Yes. Estates, retail parks and business parks around Wareside, Home Farm Industrial Park among them, are all within reach. A few photos and the unit address let us price the work.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Can you plan resealing across several buildings?
Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
What if the old mastic contains asbestos?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
Signs you need mastic sealing in Wareside
The edges of the material itself sometimes break away, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.
If one of these sounds familiar, it’s time for a closer look:
- Leaks at window and door perimeters
- Cracked, hardened mastic round windows on a block
- Damaged joints in communal entrances and corridors
- Mastic failing across several blocks on an estate
If you own or manage units on a site such as Home Farm Industrial Park (2.1 miles south of Wareside), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.
Questions to ask before you book
- Who will actually carry out the work
- Whether old or failed sealant will be cut out, not overlaid
- How the joint faces will be prepared and primed
- What the guarantee covers, and for how long
Site staff or a sealant specialist?
Redoing a failed joint usually costs more than getting it right at the outset, 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.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

- The total length or number of joints
- Which sealant the job calls for
- How much existing material needs removing
- Distance, for remote addresses
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Sending details for a quote
Diagnosis starts before we arrive. Tell us:
- Asbestos survey details if the building is older
- Photos of the joints, close up and from further back
- Whether the building will be occupied during the work
- The site address and postcode
Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to call the office on 01277 525 020 or email a schedule or drawings.
Different surfaces, different methods
Communal areas
Communal entrances, stairwells and corridors have joints at door frames, screens, skirting and floor edges. Fresh joints make shared areas look looked after.
Planned maintenance
Adding mastic to planned maintenance avoids reactive repairs and keeps budgets predictable.
Why act early in Wareside
Adding sealant to cyclical maintenance is an easy win. Waiting until leaks appear means working under pressure and less choice about when. For buildings around smaller places like Wareside, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
