Facade sealing for commercial buildings in Paulsgrove
Managing agents and owners in Paulsgrove ask us to, we reseal perimeters across whole elevations or a handful of problem windows. Either way, the method is the same: old sealant out, faces cleaned, depth set and a new bead tooled in. A 12-month guarantee applies to our workmanship. Most enquiries involve gaps between rainscreen or cladding panels and air leaks through failed facade joints, across stone and brick facade joints, window and door perimeters and coping and flashing joints. A specialist sealant contractor works differently from a general builder: in Paulsgrove, that means joint design, primers and backing rod as standard.
Building work in places the size of Paulsgrove is normally small-scale: a handful of new houses, barn conversions, a school or hall extension. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Sites and facades in and around Paulsgrove
With the shore within about 1 mile, Paulsgrove counts as a coastal location. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so we check the specified product suits the exposure before the first bead. At about 62 miles from central London, Paulsgrove is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme.
For contractors on a campus like University of Portsmouth - North Zone (3.5 miles south of Paulsgrove), facade and perimeter sealing has to fit around students and term dates. For a contractor working at a hospital such as Queen Alexandra Hospital, 1 mile east of Paulsgrove, perimeter and facade sealing is planned around patients and deliveries.

Do you need facade sealing in Paulsgrove?
New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone, and the patch soon lifts.
Look out for the following:
- Perimeter joints where frames meet the structure
- Damp patches beside frames after rain
- New sealant peeling off old mastic
- Gaps between rainscreen or cladding panels
New units and refits on sites such as Oak Park Industrial Estate, 0.6 miles south-east of Paulsgrove, need their panel and perimeter joints sealed to the specification.

Common questions from Paulsgrove clients
Is Paulsgrove too small for you to travel to?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Does the sea air around Paulsgrove change the choice of sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
What type of sealant goes on window perimeters?
It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them and we follow the specified product.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also call the office on 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Will rain stop the work?
Wet joints or temperatures outside the product’s range mean waiting. We plan for weather and keep you updated.
When to bring in a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Keeping the joints sound
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Brief window cleaners about newly sealed joints
- Walk the elevations once or twice a year
- Investigate damp beside windows promptly
- Check the asbestos register before old mastic is disturbed
Following storms, look inside for damp or staining near frames. An early report usually means a small reseal rather than a bigger repair.
Coordinate facade sealing with other external works. One set-up for several trades saves money and cuts time on site.
Leave it or put it right?
The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.
