Different surfaces, different methods
Perimeter joints at frames and structure
The joint around a framed system, where it meets the structure, needs sealant. Our work is that perimeter joint.
Precast concrete panels
Precast panel joints have to absorb thermal and structural movement. We use a sealant with the right movement capability, set over backing rod with primer where the product requires it.
About our facade sealing in Northchurch
Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters with products suited to facade or glazing perimeter joints. If you have failed seals around shopfront and entrance frames and cold air coming in at window perimeters, we can put it right, on perimeter joints where frames meet the structure, cladding panel joints and stone and brick facade joints alike. A specialist sealant contractor works differently from a general builder: on jobs in Northchurch, preparation and product choice get the time they need.
Conversions around smaller places like Northchurch often join new frames to old masonry or timber, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

- Damaged frames that need replacing

- Stone and brick facade joints
- Cladding panel joints
What happens if it’s left?
Scaffold or access already on site makes resealing much simpler. Combine it with planned external works and you only arrange access once. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Maintenance after handover
To get the most from the new sealant:
- Report water ingress at frames as soon as it shows
- Combine resealing with other works that need access
- Avoid harsh cleaners on facade sealant
- Never let anyone seal over old sealant
Include facade joints in your planned maintenance inspections. Signs to look for are cracking, edges lifting, chalking and stiffness.
Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money and cuts time on site.
Sites and facades in and around Northchurch
Several hotels sit less than 2 miles from Northchurch. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included. Rainfall across the South East, Northchurch included, is lower than in many 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 refurbishing units at places like Northbridge Road Industrial Estate, less than half a mile east of Northchurch, the mastic covers cladding panels, roller-door and window perimeters. On a healthcare site such as Hemel Hempstead Hospital, which lies east of Northchurch, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Questions about Northchurch
Can you work at a site such as Northbridge Road Industrial Estate, by Northchurch?
Yes. Estates, retail parks and business parks around Northchurch, Northbridge Road Industrial Estate among them, are all within reach. A few photos and the unit address let us price the work.
Is Northchurch too far out for you?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
How do we ask for a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Do you hold CHAS accreditation?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
What will the job cost?
There isn’t a price list, as every site differs. Send photos or drawings and we’ll price it at a fixed figure.
Our process
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts. If neighbouring businesses or buildings around Northchurch need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.
- We start with photos, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full and both faces cleaned back.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- We go over the completed work with you before leaving.
What we need from you
- For older buildings, check the asbestos register before work
- Tell us what induction or permit system the site runs
- Tell staff and tenants when we’ll be in

Common problems we fix in Northchurch
Adhesive failure, where the sealant peels away from one face, typically comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond.
Site and facilities staff are often the first to spot these:
- Cold air coming in at window perimeters
- New sealant peeling off old mastic
- Gaps between rainscreen or cladding panels
- Damp patches beside frames after rain
Projects at schools like St Mary's CofE Primary School work to term dates, so mastic is programmed tightly.
