Why it’s worth doing now in Hammersmith
If access is already up for other work, resealing at the same time makes sense. Combine it with planned external works and you only arrange access once. Getting scaffold, permits or access booked in Hammersmith takes effort, so it makes sense to deal with every failing joint while access is in place.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Facade sealing for commercial buildings in Hammersmith
Sealant around windows, doors and cladding panels stops rain reaching the wall behind. Once a perimeter seal fails, water tracks in around frames and panels. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. Site teams most often ask us about unsightly perimeter sealant on a visible elevation and cladding panel joints that have opened up, on perimeter joints where frames meet the structure, coping and flashing joints and cladding panel joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Hammersmith, preparation and product choice get the time they need.
Construction in a London area such as Hammersmith means working on constrained sites: limited storage, booked deliveries and access shared with other trades. Mastic is typically one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
We sign every job 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.

Hammersmith: questions and answers
Can you work in a London building with booked loading and goods-lift slots?
Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we’ll work to them. The ULEZ covers the whole of Greater London, which we allow for
Is Berghem Mews Business Village, near Hammersmith, within your area?
Yes, sites like Berghem Mews Business Village are within our area, along with the rest of Hammersmith. Photos and a short description are enough for a first look.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Should we check old sealant for asbestos?
For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder, so ask for it before we start. If asbestos is suspected, work stops until it is tested.
Are your applicators CSCS-carded?
Yes. If you need card details for site access, tell us and we will confirm them with the quote.
Will you check whether the sealant is causing the leak?
Yes. We check the sealant joints and report what we find as part of pricing. If the water seems to come from a roof, sill or the glazing unit instead, we say so.
How do we ask for a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

What affects the price in Hammersmith
Before we quote, we look at:
- How much existing material needs removing
- Access and working height
- The size and state of each joint
- Travel to remote or island sites
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.
Before you send an enquiry
To price the job accurately, we need to understand the site. Useful things to include:
- What the building is and how it’s used
- The asbestos register, for older buildings
- Anything awkward about access or site hours
- Any dates the work must fit around
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or speak to us on 01277 525 020 or email the details over to discuss it first.
Facades, frames and programmes in Hammersmith
The ULEZ covers the whole of Greater London, Hammersmith included, so site vehicles need to meet its standards or pay the daily charge. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. Hammersmith has a good number of hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
Projects at colleges like St Mellitus Theological College, 1.8 miles to the east of Hammersmith, tend to run to term dates, so the mastic is planned tightly. Hospital estates such as Charing Cross Hospital (to the south-east of Hammersmith) 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. On a campus such as Polish University Abroad, under half a mile south-east of Hammersmith, new teaching buildings and residences are normally built and refurbished around the academic year.
Hammersmith is about 1 mile west of Kensington, in Greater London. We cover Hammersmith, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Greater London coverage takes in 764 places, large and small. There’s a separate page for London, about 6 miles away.
We cover the W6, W14, W12 and W4 postcode districts for facade joints. Among the streets we cover are The Square, Ravenscourt Square and Westcroft Square. Nearby places we also cover include Brackenbury Village (1 mile north-west), Brook Green (1 mile east), North End (1 mile east), West Kensington (1 mile east) and Old Chiswick (1 mile south-west). A short drive away, we cover London (6 miles east), City of Westminster (4 miles east), Marylebone (4 miles north-east), St Pancras (5 miles north-east), Shoreditch (7 miles east) and Walthamstow (11 miles north-east).

For managing agents and facilities managers
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
General trades versus a specialist
Some joints are best left to specialists: for instance 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.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What the job involves on each surface
Cladding panel joints
On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end to the correct depth.
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. These joints take full exposure to weather.
From enquiry to sign-off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you. All of Greater London is in the ULEZ, and kerbside space in Hammersmith can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- Failed beads are removed in full.
- Primer goes on where the product data asks for 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.
Preparing the site
- Tell staff and tenants when we will be in
- Tell us your opening times and when work is allowed
- Make sure the joints can be reached
