Mastic sealing in Exnaboe
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Our applicators are CSCS-carded, and the work is backed by public liability insurance. Resealed mastic joints in Exnaboe carry our 12-month guarantee. We work on shopfronts below residential blocks, window and door perimeters on blocks and balcony and threshold joints, and what we are called in for most is water getting in round frames after rain and draughts at frames across a block. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Exnaboe is the same: the right product in a properly prepared joint.
Around smaller places such as Exnaboe, buildings managed by landlords and associations are often small groups of flats, sheltered housing and halls. Frames on exposed elevations are where mastic usually fails first.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When it isn’t the sealant
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Broken glass or failed sealed units
- Frames that are rotten, warped or broken
- Asbestos-containing sealant, which we don’t remove
If you’re not sure, just ring 01277 525 020 or email the details over and we’ll give you a straight answer.
Surfaces we seal
- Shopfronts below residential blocks
- Balcony and threshold joints
- Communal entrances and stairwells
- Communal kitchens and washrooms
- Window and door perimeters on blocks
- External wall and movement joints
Surface by surface
Commercial and mixed-use buildings
Tenants in commercial buildings need to keep trading, so we plan around them.
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
Common questions from Exnaboe clients
Can you take on a job in Exnaboe, on the island?
Yes. Islands are part of our area, Exnaboe included. Island work is planned around ferry crossings and the weather, so photos and a full list before we travel are essential.
Will you price a mastic programme across our Exnaboe portfolio?
Yes. Portfolio-wide programmes are a regular request. Send the addresses and photos and we’ll give a fixed quote.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.
How do you choose the sealant?
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.
Can you take on resealing for a block portfolio?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Do you supply RAMS and insurance details?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.

Site staff or a sealant specialist?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

After the work
Problems stay small when the joints are checked regularly. In particular:
- Have the asbestos survey to hand for older buildings
- Prioritise elevations facing the weather
- Make it easy for occupiers to report draughts
- Share your contractor requirements early
Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.
Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first.
