Facade sealing for commercial buildings in Dartmouth Park
Managing agents and owners in Dartmouth Park ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: old sealant out, faces cleaned, depth set and a new bead tooled in. A 12-month guarantee applies to our workmanship. If you have facade joints cracked through the middle and discoloured or dirty facade joints, we can help, whatever the surface. Whoever orders the work in Dartmouth Park, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Building sites in London tend to be tight: limited storage, booked deliveries and access shared with other trades. Mastic is usually 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.

Why it’s worth doing now in Dartmouth Park
A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Water through a failed joint rarely stays where it starts, often turning up far from the joint. Failed sealant in a building in Dartmouth Park can quickly affect neighbours, tenants or the floor below. Dealing with it early is simpler for everyone.
Pricing facade joints depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.

Common questions from Dartmouth Park clients
Would you work within a site like The Whittington Hospital?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Does your area include sites such as Bush Industrial Estate, near Dartmouth Park?
Yes. Our area takes in Dartmouth Park and its surroundings, with estates and business parks such as Bush Industrial Estate included. To start, just call the office on 01277 525 020 or email us with the unit, the joints involved and your access times.
Can the sealant be colour-matched?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Will you check whether the sealant is causing the leak?
Yes. Photos help, and you can call the office on 01277 525 020 or email the details over to arrange a visit. Failed perimeter sealant is a common cause, but not the only one.

Surface by surface
Cladding panel joints
Panel joints on cladding and rainscreen systems take movement every day. We use a product rated for the movement and suited to the panel surface, often a low-modulus silicone or hybrid.
Window and door perimeters
Aluminium, PVC-U and timber frames each have their own preparation needs. We clean and prime to the sealant maker’s guidance for each surface.
Commercial clients in Dartmouth Park
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Should maintenance staff do it?
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Facade sealing around Dartmouth Park: how the place shapes the job
A 2-mile radius around Dartmouth Park takes in plenty of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Dartmouth Park. Deliveries are booked and storage is tight, so mastic materials come in as needed.
Further education sites such as Working Men’s College (to the south-east of Dartmouth Park) are extended and refurbished from time to time, with mastic often programmed into the summer break. Recladding or extending a unit at a site like Bush Industrial Estate (to the east of Dartmouth Park) brings panel joints and frame perimeters into the programme. On a campus such as American University in London (1.2 miles east of Dartmouth Park), new teaching buildings and residences are usually built and refurbished around the academic year.

Diagnose, treat, sign off
Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. In Dartmouth Park, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Have the specification and drawings to hand
- Warn occupants and staff about the work
