Mastic sealing across Fair Oak
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Mastic sealing for commercial buildings in Fair Oak
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. If you are dealing with draughts at frames across a block and the same joint failures repeated across a portfolio, we can put it right, on external wall and movement joints, communal kitchens and washrooms and communal entrances and stairwells alike. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Fair Oak is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Older buildings and conversions around places like Fair Oak mix old masonry with newer frames. Perimeter joints need a sealant that suits both frame and masonry.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Questions about Fair Oak
Is a smaller place like Fair Oak outside your area?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Can you quote for a block close to Hedge End station?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
Do you supply RAMS and insurance details?
Our credentials include CHAS, Constructionline and public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you reseal a whole block or estate?
We can. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
Is mastic sealing guaranteed?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
Leave it or put it right?
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. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

How the quote is worked out
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Site requirements such as inductions and permits
- Specialist products, such as fire-rated or hygienic sealants
- Distance, for remote addresses
- Working within restricted access windows
A quote for mastic joints depends on quantities, condition and access, plus any specification you are working to. Call for a quote.
What we need to price the job
It doesn’t need to be a full survey. A few details are enough to get going:
- Any specification or named product
- Your programme or deadline
- Approximate linear metres or a joint schedule
- What the building is and how it’s used
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.
What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Asbestos-containing sealant, which we don’t remove
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Substrate edges that need repairing first
Not sure which it is? You can call 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

Planned mastic for Fair Oak portfolios
Fair Oak sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. At about 64 miles from central London, Fair Oak is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide.
Churches, halls and community buildings such as Saint Thomas are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Buildings close to stations like Hedge End station, 2.2 miles to the south of Fair Oak, are often flats over shops, with frame mastic to keep sound. Site managers at schools like Fair Oak Junior School can fit frame mastic into the summer works.
