Your questions answered
Do you take on work at healthcare sites like Hartswood Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can work at a site such as Havering Technical College fit around teaching?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Do you cover South Weald?
Yes. Sites across South Weald are covered, and the same phone number covers every area.
Do you install glazing systems?
No. We don’t install glazing systems, windows or glass. We seal the joints around them, including perimeters where frames meet the structure.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
Facade sealing in South Weald, done properly
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. If you are dealing with perimeter joints where frames meet the structure and new sealant peeling off old mastic, we can help, whatever the surface. Most enquiries from South Weald start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Construction in and around smaller places such as South Weald 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.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Sites and facades in and around South Weald
South Weald is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager. The area within 2 miles of South Weald holds a number of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
When a school such as Holly Trees Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Units on estates such as Warley Hill Business Park (to the south-east of South Weald) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
South Weald is about 2 miles west of Brentwood, in Essex. Anywhere in CM14, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 644 places across Essex fall within our area, including South Weald. London is covered too, some 18 miles away.

On site: what to expect
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Jobs in and around smaller places like South Weald are typically planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- Access, site rules and timing are settled with the client up front.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.
- Faces are cleaned, primed where needed and backed.
- Sealant is gunned in and tooled hard onto both faces.
- We hand over with our 12-month workmanship guarantee.
Getting the site ready
- Arrange parking or a loading space
- Tell staff and tenants when we will be in
- Point out any areas we must not close

Common problems we fix in South Weald
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, and movement soon pulls it away.
It’s worth sending us details if you spot any of the following:
- Damp patches beside frames after rain
- Air leaks through failed facade joints
- Failed seals around shopfront and entrance frames
- Hard, chalky sealant that no longer flexes
For a contractor working at a hospital such as Hartswood Hospital, 1.8 miles to the south-east of South Weald, perimeter and facade sealing is planned around patients and deliveries.
What to look for in a quote
- Whether their applicators hold CSCS cards
- How long is the guarantee, and what does it include?
- Are they CHAS accredited or on Constructionline?
- How the joint faces will be prepared and primed
When it isn’t the sealant
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Render or concrete edges that have broken away
- Water getting in through cracked render or porous masonry
- Specialist high-level access methods
Not sure which it is? You can call 01277 525 020 or email the details over and we’ll tell you honestly.
Surfaces we seal
- Perimeter joints where frames meet the structure
- Cladding panel joints
- Shopfront frames
- Coping and flashing joints
- Stone and brick facade joints
- Window and door perimeters
Cost factors for facade joints
The price varies from site to site. It mainly depends on:
- Distance, for remote addresses
- Quantities, in metres or numbers
- Working within restricted access windows
- How much existing material needs removing
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Details that help us quote
We can often quote from photographs and a few details. It helps to include:
- Anything awkward about access or site hours
- The site address and postcode
- Approximate linear metres or a joint schedule
- Any dates the work must fit around
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or call the office on 01277 525 020 or email drawings and photos to discuss it first.
Why act early in South Weald
Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. For buildings around smaller places like South Weald, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.

When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
