Facade sealing in Navestock Heath
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Different surfaces, different methods
Cladding panel joints
Joints between cladding panels open and close with temperature. We use a product rated for the movement and suited to the panel surface.
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, not the framing or glazing itself.
Facade sealing for commercial buildings in Navestock Heath
External sealing depends on the weather more than most trades. Joints have to be dry and the air and surface temperature within the product’s range. We plan for that and keep you updated. We work on shopfront frames, cladding panel joints and coping and flashing joints, and what we’re called in for most is cladding panel joints that have opened up and sealant pulling away from frames or panels. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Navestock Heath it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Construction in and around smaller places such as Navestock Heath is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

When it isn’t the sealant
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Movement beyond what any sealant can handle
- Damp caused by condensation inside the building
- Render or concrete edges that have broken away
If you are not sure, just call the office on 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.

Common problems we fix in Navestock Heath
Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, then it splits or peels.
Things that normally lead to an enquiry:
- Unsightly perimeter sealant on a visible elevation
- Sealant pulling away from frames or panels
- Water coming in around window frames
- Draughts around frames and panels
Hospital estates such as Suttons Manor Hospital, 1.6 miles west of Navestock Heath, 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.

Building and refurbishing in Navestock Heath
Navestock Heath is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team. Navestock Heath lies roughly 17 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes.
Historic houses such as Hill Hall, 3.2 miles to the north-west of Navestock Heath, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. Further education sites such as Havering Technical College (2.9 miles south of Navestock Heath) are extended and refurbished from time to time, with mastic often programmed into the summer break.
Navestock Heath is about 4 miles north-west of Brentwood, in Essex. Navestock Heath sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Our Essex coverage takes in 644 places. Sites around London have their own page, roughly 17 miles from Navestock Heath.

Maintenance after handover
A few simple habits keep the new joints working:
- Clear debris that holds water against joints
- Don’t wait for a second leak before calling
- Avoid harsh cleaners on facade sealant
- Never let anyone seal over old sealant
Keep a note of which product went in and when. It helps when matching repairs or planning the next reseal.
Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos.
Our process
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area.

Advice
Common questions from Navestock Heath clients
Is hospital work, at somewhere like Suttons Manor Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Is Navestock Heath off your patch?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
What type of sealant goes on window perimeters?
Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Some joints call for hybrid, PU or polysulphide instead, as the specification or substrate requires.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
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.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
Work for main contractors and building owners
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
