Facade sealing for businesses in Clayhall
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What sets the cost
Each job is priced on its own details. The things that drive the figure:
- How much there is to seal
- Backing rod, priming and other preparation
- Location, for remote and island sites
- The product specified
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.
Details that help us quote
Whether it’s one area or a whole building, the same details help:
- Specification clauses that apply
- When you need the work done
- How the joints are reached, and at what height
- Where the site is, with the postcode
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.
Facade sealing in Clayhall
Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around, and we will fit the work around it. We work on window and door perimeters, stone and brick facade joints and cladding panel joints, and the usual reasons a site gets in touch are patch repairs that keep failing and failed sealant on precast panel joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Clayhall, preparation and product choice get the time they need.
On a small site around Clayhall, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we’ll time the work so nothing waits on us.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

On site: what to expect
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and we clear our waste as we work. If neighbouring businesses or buildings around Clayhall need work too, visits can be combined. Tell us your site hours and we will plan around them.
- We plan access and the order of elevations with the client.
- We only seal when joints are dry and within the product’s temperature range.
- 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.
What we need from you
- Confirm the product named in the specification
- For older buildings, check the asbestos register before work
- Tell us which areas need to stay in use

Doing it in-house
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
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. That’s why many clients bring in a specialist from the beginning.
For managing agents and facilities managers
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Clayhall can form part of a wider programme.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Your questions answered
Our building in Clayhall is near the coast: does that change the sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Will you take on work at estates like QinetiQ Haslar Marine Technology Park, close to Clayhall?
Yes. We cover Clayhall and the area around it, including industrial estates, business parks and retail parks such as QinetiQ Haslar Marine Technology Park. Send details of the unit and the work through our quote form for a quick quote.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Can you work in cold or wet weather?
Wet joints or temperatures outside the product’s range mean waiting. The programme allows for it and we tell you if the forecast changes things as the work goes on.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
Do you use silicone for external joints?
It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing and we follow the specified product.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.

Contractors’ notes for Clayhall
Clayhall is within about 1 mile of the coast. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager.
For contractors on a campus like University of Portsmouth - North Zone, which lies north-east of Clayhall, facade and perimeter sealing has to fit around students and term dates. Hospital estates such as Gosport War Memorial Hospital (to the north-west of Clayhall) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
Clayhall is about 2 miles south-east of Gosport, in Hampshire. Our applicators travel to Clayhall for work on facade joints. Clayhall is one of 723 places in Hampshire on our list for facade joints.

Maintenance after handover
For the best life from the joints:
- Inspect facade joints on a regular cycle
- Report water ingress at frames as soon as it shows
- Share access with other external trades
- Check that rainwater leaves the facade the way it was designed to
Blocked sills and gutters push water at the joints. Sealant copes better when water runs off the facade as designed.
Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it, and if it’s suspected, we stop until it has been tested.
Signs you need facade sealing in Clayhall
New sealant run over old sealant rarely holds. Cured silicone won’t accept a new silicone bead, and the patch soon lifts.
If one of these sounds familiar, it’s time for a closer look:
- Old perimeter mastic that has dried out
- Cold air coming in at window perimeters
- Leaks at window and door perimeters
- Staining on stone next to old sealant
Units on estates such as QinetiQ Haslar Marine Technology Park, under half a mile north-east of Clayhall, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Questions to ask before you book
- Are they CHAS accredited or on Constructionline?
- Which product they’ll use, and why it suits the joint
- How joint depth will be controlled
- What site paperwork they can supply
