Doing it in-house
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Facade sealing for commercial buildings in St Helens
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 facade joints cracked through the middle and old perimeter mastic that has dried out, we can put it right, on shopfront frames, cladding panel joints and stone and brick facade joints alike. Facilities teams, main contractors and managing agents in St Helens tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Construction in and around smaller places such as St Helens 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.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Questions we are asked in St Helens
Is a smaller place like St Helens outside your area?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Is Ryde Business Park, near St Helens, within your area?
Yes, sites like Ryde Business Park are within our area, along with the rest of St Helens. Photos and a short description are enough for a first look.
Can you look at water coming in around a frame?
Yes. We look at the perimeter sealant and tell you whether it has failed. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Do you offer coloured sealant?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
What we are called out for in St Helens
The wrong product causes its share of trouble: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Most external joints call for a neutral-cure, facade-grade sealant.
Common reasons buildings call us in:
- Water coming in around window frames
- Sealant pulling away from frames or panels
- Draughts around frames and panels
- Perimeter joints where frames meet the structure
For a contractor at a hotel such as The Priory Bay Hotel, 0.8 miles to the north of St Helens, the mastic often has to be finished before a reopening date.
Questions to ask before you book
- How the joint faces will be prepared and primed
- Is the sealant right for the movement and the substrate?
- Can the work be phased to keep areas open?
- How they handle RAMS and site documents
Honest limits
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Damp caused by condensation inside the building
- Render or concrete edges that have broken away
- Specialist high-level access methods
Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we’ll tell you honestly.

What the job involves on each surface
Window and door perimeters
Frames grow and shrink with temperature, and the perimeter joint has to follow. Rod placed at the right depth lets the bead stretch without tearing.
Coping and flashing joints
Sometimes the coping or flashing itself has failed. We tell you if the fix is a roofing or metalwork job rather than a reseal.
Mastic packages on St Helens sites
With the shore within about 2 miles, St Helens counts as a coastal location. Coastal exposure means perimeter and cladding joints work harder than on an inland job, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. St Helens sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager.
Hospital estates such as Arthur Webster Memorial Hospital for Children, 5.3 miles to the south-west of St Helens, 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. When a school such as St Helens Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.
