Looking after the joints
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Make sure contractors see the asbestos survey before cutting out old mastic
- Log reseals in the O&M or maintenance records
- Check sealant as part of routine building inspections
- Have extract fans checked so wet areas dry out
Brief your cleaning team on the joints that have been resealed. Scourers, blades and harsh products shorten a bead’s life.
Sealant rarely fails all at once across a building. A few splits this year usually mean more next year. We will tell you which sealant joints need doing first and which can wait.
Your questions answered
Which documents can you supply for work in Sand Hill?
We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.
Can the sealant on our Sand Hill premises match the finishes?
Yes, we can normally get close to most finishes from the product’s colour range. Send colour references or photos and we will confirm what’s available for the product.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
How many days will you need on site?
It depends on the scope, but the work usually takes part of a day on a small job and longer where several buildings or phases are involved. For bigger or phased jobs, we will set out a timescale with the quote.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Could the old sealant in an older building contain asbestos?
In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. Before cutting anything out, we ask for the asbestos register or survey, and if something is suspected, work stops until it’s tested.
Signs you need commercial sealant contractors in Sand Hill
A split down the middle of the bead tells a different story. That usually means the joint stretched further than the product could cope with. The same product in the same joint tends to fail the same way, which is why we look at the joint design as well.
Typical triggers for a call:
- Smeared sealant across finishes from a rushed job
- Expansion joints with the sealant torn out
- Water staining near frames, panels or ceilings
- Earlier reseals applied straight onto the failed bead
Colour matters on frontages and fit-outs, so the quote confirms which colours the chosen product comes in.
Questions to ask before you book
- How the existing material will be dealt with
- Whether primer will be used where the manufacturer specifies it
- Who will actually carry out the work
- Their plan for phasing and protecting the area
How a job runs
At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Sand Hill, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- We start with the evidence: photographs, drawings or a look on site.
- A fixed quote follows, with removal and preparation included.
- We agree the order of work, access windows and site hours with you.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Depth is set with backing, then the sealant is applied, tooled and the area tidied.
- Completed areas are signed off with you under our 12-month guarantee.
Getting the site ready
- Flag any permit to work we’ll need
- Send your site hours and access windows
- Make sure the joints can be reached

What happens if it’s left?
Patching the worst lengths can be the right call on a tight budget. Where the remaining sealant is just as old, it tends to fail soon after, so access and set-up end up being paid for twice. We can price both options so you can decide on the facts. Converted and older buildings near places like Sand Hill tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Working on commercial sites near Sand Hill
Sand Hill lies roughly 40 miles out from central London. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Occupiers with several premises in the region tend to prefer one contractor and one point of contact. Sand Hill sits in one of the drier corners of the country, the South East. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up.
Whatever the building in Sand Hill, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material.
