Mastic sealing in Three Ashes
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What we can’t put right
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Water coming in from the roof or rainwater goods
- Masonry that has broken away beside the joint
- Broken glass or failed sealed units
Not sure which it is? You can give us a call on 01277 525 020 or email the details over and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Window and door perimeters on blocks
- Shopfronts below residential blocks
- Balcony and threshold joints
- Communal kitchens and washrooms
- Communal entrances and stairwells
- External wall and movement joints
Mastic sealing in Three Ashes, done properly
On a residential block, the work happens around people’s lives. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Entrances and stairwells are kept in use throughout. If you are dealing with water getting in round frames after rain and repeated reactive repairs to the same buildings, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Three Ashes is the same: the right product in a properly prepared joint.
Around smaller places like Three Ashes, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why deal with it now?
Leaving failed external joints lets water reach the structure behind. That can lead to damp, staining and damage to finishes, which is harder to deal with than resealing. Older rural buildings around Three Ashes move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

What else we do in Three Ashes
General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
How a job runs
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like Three Ashes are typically planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.
- A building-by-building inspection lists the failed joints.
- The quote is fixed and split as suits you.
- We agree the programme and dates with you.
- Failed sealant is removed and the faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.
Before we start on site
- Point out parking and an unloading spot
- Flag any permit to work we will need
- Make sure the joints can be reached

Advice
Aftercare for building managers
Cleaning and maintenance staff play a part too. Pass these on to them:
- Reduce knocks to communal area joints
- Have the asbestos survey to hand for older buildings
- Log resealing dates block by block
- Encourage occupiers to report problems at frames
Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.
Cost factors for mastic joints
A fixed quote reflects the actual work. It allows for:
- The total length or number of joints
- Access and working height
- Phasing around occupants
- Travel to remote or island sites
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
What to include in your enquiry
Diagnosis starts before we arrive. Let us know:
- Specification clauses that apply
- The postcode of the building
- Anything awkward about access or site hours
- What the building is and how it’s used
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Your questions answered
Will you take on a block within reach of Bramley (Hants) station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.

When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
What guarantee do you give on resealing?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
Do you seal on top of existing 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.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
