Questions we’re asked in Chale Green
Does a coastal location like Chale Green affect which sealant is used?
It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.
Is hospital work, at somewhere like Whitecroft Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Can you work while the building is occupied?
In most cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
How do we ask for a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
How we handle expansion joint sealing in Chale Green
Every structure moves a little, all the time: they expand in the heat, shrink as they dry, and shift under load. Movement joints are where that movement is absorbed, and the sealant in them keeps water and debris out. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors for buildings in Chale Green. We work on cladding panel joints, podiums and floor movement joints and car park decks and ramps, and the failures we are asked to look at most are car park joints leaking onto vehicles below and expansion joints filled with dirt and stones. Looking for mastic applicators who cover Chale Green? Mastic Doctor has worked for contractors, FMs and building owners since 2005.

When to bring in a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Why deal with it now?
A torn seal left alone normally gets worse. Water and debris get in, the joint jams and the edges spall and the job grows to repairs as well as sealing. Resealing early keeps the work to sealant. Converted and older buildings near places like Chale Green tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Keeping the joints sound
Your facilities or cleaning team can help the joints last. Share these points with them:
- Act on the first tear or lifting edge rather than waiting
- Keep traffic off new joints until the cure time is up
- Inspect movement joints alongside other routine building checks
- Brief car park operatives to protect joint lines during winter clearance
Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears. A routine sweep is the simplest protection.
Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint. Resealing promptly prevents internal damage.
Floors, slabs and movement joints in Chale Green
The sea is no more than about 2 miles from Chale Green. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, so a failed joint lets more in and the edges break up sooner. Chale Green sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.
Large sites such as Whitecroft Hospital (to the north of Chale Green) have car parks, service roads and long elevations with movement joints in brick and panels.

Surface by surface
Joints between different materials
Different materials meeting at a joint rarely move in step. We choose a sealant that grips both faces.
Car park decks and ramps
Deck and ramp joints take tyre loads, grit and de-icing salts. A trafficable sealant suited to the movement goes in, phased so parts of the car park stay open.
