About our facade sealing in Glassenbury
External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits. We build that into the programme and tell you if the forecast changes the plan. The enquiries we see most involve failed sealant on precast panel joints and previous reseals run over old sealant, on coping and flashing joints, shopfront frames and cladding panel joints. Looking for mastic applicators who cover Glassenbury? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
For a site near Glassenbury, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What sealant work can’t fix
Honesty saves time and money. Fresh joints won’t solve:
- Specialist high-level access methods
- Water getting in through cracked render or porous masonry
- Damaged frames that need replacing
Not sure which it is? You can call 01277 525 020 or email the details over and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Perimeter joints where frames meet the structure
- Stone and brick facade joints
- Coping and flashing joints
- Shopfront frames
- Cladding panel joints
- Window and door perimeters
Different surfaces, different methods
Precast concrete panels
Concrete edges can be dusty or weak. We clean back to sound material and flag edges that need repair before sealing.
Window and door perimeters
Frames grow and shrink with temperature, and the perimeter joint has to follow. The rod limits depth, leaving the bead able to flex.

Glassenbury: questions and answers
Can you work on a hospital site such as Benenden Hospital?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Is a smaller place like Glassenbury outside your area?
Not at all. Glassenbury is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Can you work in cold or wet weather?
Year-round work is possible as long as joints are dry and temperatures suit the product. Frost and condensation on glass and steel are common on winter mornings, so we plan around the forecast.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Do you provide access for facade work?
Access is planned with you before we quote. Let us know what access is in place or planned, and the quote will reflect it.
Diagnose, treat, sign off
Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Rural sites near Glassenbury may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- Access, site rules and timing are settled with the client up front.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.
- Faces are cleaned, primed where needed and backed.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- We hand over with our 12-month workmanship guarantee.
Before we start on site
- Tell us which areas need to stay in use
- Move anything stored against the joints
- Share your working hours and any access restrictions

Why it’s worth doing now in Glassenbury
Topping up a failed joint normally buys very little time. A full cut-out and reseal costs more on the day but lasts much longer and avoids repeat call-outs. Around Glassenbury, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Why appoint us
- Joints cleaned back to sound surfaces
- Colour options checked against the specified product
- Standard and matched colours in many product ranges
- 12 months’ guarantee on every job

When to bring in a specialist
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
