Mastic sealing for commercial buildings in Baffins
We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed and backing rod used wherever a joint is deep. We work on communal entrances and stairwells, shopfronts below residential blocks and window and door perimeters on blocks, and the usual reasons a site gets in touch are window mastic that has split and shrunk and occupiers reporting cold air round windows. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Baffins is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Owners with buildings around smaller places like Baffins often group mastic work so one visit covers several properties. One quote can cover a whole list of addresses.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Do you need mastic sealing in Baffins?
We often find joints filled solid with no backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and splits as the building moves.
If one of these sounds familiar, it’s time for a closer look:
- Old repairs sealed over failed mastic
- Damaged joints in communal entrances and corridors
- Water getting in round frames after rain
- Window mastic that has split and shrunk
Churches, halls and community buildings such as Church of St Cuthbert are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
What to look for in a quote
- Will failed sealant be removed rather than covered?
- The named product and why it was chosen
- Their approach to joint depth and backing
- How they handle RAMS and site documents
When to bring in a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
What affects the price in Baffins
A fixed quote reflects the actual work. It allows for:
- Joint width, depth and condition
- Specialist products, such as fire-rated or hygienic sealants
- How accessible the joints are
- How much existing material needs removing
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
Sending details for a quote
Good information means a firmer quote. When you get in touch, include:
- The type of building and who uses it
- Approximate linear metres or a joint schedule
- Any dates the work must fit around
- Anything awkward about access or site hours
For a fixed quote, phone 01277 525 020 or email us, telling us the site location and the nature of the job. You can also send details through our quote form.
When it isn’t the sealant
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Glazing that needs replacing
- Asbestos-containing sealant, which we don’t remove
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
If you are not sure, just speak to us on 01277 525 020 or email drawings and photos and we’ll give you a straight answer.
Surfaces we seal
- Shopfronts below residential blocks
- Window and door perimeters on blocks
- External wall and movement joints
- Balcony and threshold joints
- Communal entrances and stairwells
- Communal kitchens and washrooms
Maintenance after handover
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- List the paperwork your organisation requires when you send details
- Plan resealing building by building rather than complaint by complaint
- Have the asbestos survey to hand for older buildings
- Reduce knocks to communal area joints
Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.
Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.

Baffins: questions and answers
Is Baffins too far out for you?
No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
