Facade sealing for Langstone sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For a building around Langstone, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
What we need from you
- Arrange parking or a loading space
- Send any specification or drawings in advance
- Tell us what induction or permit system the site runs

Facade sealing in Langstone, done properly
A good facade joint depends on design as much as product. The width has to suit the expected movement and the sealant’s movement capability, while rod fixes the depth and stops the bead sticking to the rear, often at around 2:1 width to depth, as the manufacturer advises. We work on window and door perimeters, cladding panel joints and coping and flashing joints, and the usual reasons a site gets in touch are previous reseals run over old sealant and leaks at window and door perimeters. Searching for sealant specialists in Langstone? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Sites around smaller places like Langstone can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photos and the programme and we will quote to suit.
Our workmanship is guaranteed for 12 months, in Langstone as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Your questions answered
Will you plan work around the academic year at somewhere like University of Portsmouth - Langstone Campus?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Does the sea air around Langstone change the choice of sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Do you replace windows or glass?
No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, such as perimeter joints where frames meet the structure.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Do you guarantee your work?
Yes. Workmanship is guaranteed for 12 months on every job.
Do you use silicone for external joints?
Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, depending on the substrate and the specification.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Different surfaces, different methods
Perimeter joints at frames and structure
Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. We seal those perimeter joints rather than the system it surrounds.
Render and coated surfaces
Rendered and painted facades need a sound edge for the sealant to bond to. We remove flaking material so the bead bonds to a firm surface, and areas needing repair are flagged.
Cost factors for facade joints
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Whether old sealant has to be cut out first
- Induction, permit and paperwork requirements
- The size and state of each joint
- Distance, for remote addresses
A quote for facade joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
What we need to price the job
It doesn’t need to be a full survey. These details are enough to start:
- Approximate linear metres or a joint schedule
- Any dates the work must fit around
- Whether an asbestos survey exists
- What the building is and how it’s used
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
Signs you need facade sealing in Langstone
New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone.
These are often picked up first by site or facilities staff:
- Cladding panel joints that have opened up
- Weathered facade joints that have lost their grip
- Facade joints cracked through the middle
- Unsightly perimeter sealant on a visible elevation
For a contractor at a hotel such as Langstone Hotel (0.6 miles north of Langstone), the mastic often has to be finished before a reopening date.

What happens if it’s left?
Failed joints let in more than water: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. Converted and older buildings near places like Langstone tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
