Mastic sealing in Ardheisker
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
When it isn’t the sealant
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Water coming in from the roof or rainwater goods
- Materials that need asbestos testing before work
- Glazing that needs replacing
Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we will tell you honestly before you book.
What we seal
- Balcony and threshold joints
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- Communal entrances and stairwells
- Window and door perimeters on blocks
- External wall and movement joints
About our mastic sealing in Ardheisker
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. We work on communal kitchens and washrooms, shopfronts below residential blocks and external wall and movement joints, and the failures we’re asked to look at most are no planned programme for sealant and draughts at frames across a block. One point of contact handles commercial sealant work in Ardheisker from the first photos to the final walk-round, for single jobs and planned programmes alike.
Around Ardheisker, outside mastic waits for dry weather and the right temperature. We agree a window with some flexibility.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. 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.
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
How the job changes by surface
External movement joints
The joint width has to suit the movement and the sealant’s capability, often around 2:1 width to depth, as the manufacturer advises.
Planned maintenance
Adding mastic to planned maintenance avoids reactive repairs and spreads the work.
Your questions answered
Can being near the sea in Ardheisker affect the sealant we need?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Will you price a mastic programme across our Ardheisker portfolio?
Yes, we quote for single buildings and for programmes across several blocks. Send the addresses and photos and we’ll give a fixed quote.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Is mastic sealing guaranteed?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.
How many days will you need on site?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
Why act early in Ardheisker
Looking at mastic during planned maintenance costs little. Leaving it until there’s a leak turns it into reactive work with less control over timing. Renewing every failing joint on one visit is the sensible approach for a place like Ardheisker. Photos of each area help us quote the whole job.
What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote once you have the details.

Aftercare for building managers
Once the work is signed off, a little attention goes a long way:
- Prioritise elevations facing the weather
- Track which buildings were done and when
- Check the asbestos register before any old mastic is disturbed
- Share your contractor requirements early
If paintable sealant was used, decoration can follow once it has cured. Silicone typically can’t be painted, so keep decorators off it unless told otherwise.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and saves internal repairs.
How a job runs
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself typically taking anything from a day to a few weeks, depending on the number of buildings and joints. Tell us who will meet us and how to get in at your building near Ardheisker. We will confirm the plan with the fixed quote.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- Buildings are completed in turn.
Preparing the site
- Tell us which areas need to stay in use
- Arrange parking or a loading space
- For older buildings, check the asbestos register before work
Getting a fixed quote
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
