Mastic packages on Porchfield sites
With the shore within about 2 miles, Porchfield 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. The South East is one of the drier parts of the UK. 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.
Hospital estates such as Mr Rohan Sawant (St Mary’s Hospital) (2.9 miles east of Porchfield) 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. Older buildings in the area around Porchfield, such as Swainston Manor, 2.2 miles to the south of Porchfield, need care when sealed: the product has to suit soft or historic materials. For contractors refurbishing units at places like Porchfield Business Park, 0.9 miles south-west of Porchfield, the mastic covers cladding panels, roller-door and window perimeters.

Construction mastic for commercial buildings in Porchfield
On refurbishments, the mastic package normally includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old. New and existing joints then get the same preparation. The enquiries we see most involve bath and shower joints scraped during the final clean and a long mastic snag list close to completion, on window and door perimeters, internal decorators’ caulk and brick and block movement joints. One point of contact handles commercial sealant work in Porchfield from the first photographs to the final walk-round, whether it’s one building or several.
Around smaller places like Porchfield, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

General trades versus 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.
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. For that reason, many FMs and contractors use a sealant specialist from the outset.

Maintenance after handover
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Keep scrapers and abrasive pads off new beads
- Share drawings and the specification as soon as possible
- Stick to the specified sealant rather than a generic substitute
- Record the products used in the O&M file
Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead so keep them off the joints.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Water gets behind trays, vanity tops and panels, leaving the remedial work to the contractor. Proper preparation, with the right silicone first time, keeps it off the defects list.
For managing agents and facilities managers
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
From enquiry to sign-off
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Jobs in and around smaller places like Porchfield are normally planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- First we take quantities off the drawings and read through the specification.
- You receive a fixed quote listing scope, products and phasing.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- We seal each plot or floor as it’s released to us.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Getting the site ready
- Let us know about inductions and permits
- Make sure the joints can be reached
- Confirm the product named in the specification

Advice
Questions we are asked in Porchfield
Does a coastal location like Porchfield affect which sealant is used?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Can you take on a job at a hospital such as Mr Rohan Sawant (St Mary’s Hospital)?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Will you stick to the specified products?
Specification first, then the maker’s instructions. Primers, backing and joint depth follow what the manufacturer sets out.
What hours do you work?
Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
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’ll confirm the colours available for the specified product.
Can fire-rated sealing at service penetrations be included?
It can be part of the package where specified. Tell us what records you need and we will confirm with the quote.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.
How the quote is worked out
To price the job, we consider:
- The product specified
- Site requirements such as inductions and permits
- Any access equipment needed
- Distance, for remote addresses
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
What to include in your enquiry
A good diagnosis starts with the right details. Let us know:
- Any specification or named product
- Drawings or a marked-up plan, if available
- The postcode of the building
- Asbestos survey details if the building is older
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Damage to finishes by other trades after we’ve sealed
- Joint design decisions that belong to the architect or engineer
- Deciding which fire-stopping product a penetration needs
If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we will say what we think before you book.
