Facade sealing for commercial buildings in Maida Vale
Sealant around windows, doors and cladding panels stops rain reaching the wall behind. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. We work on perimeter joints where frames meet the structure, coping and flashing joints and shopfront frames, and the usual reasons a site gets in touch are cold air coming in at window perimeters and facade joints cracked through the middle. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Maida Vale, that means joint design, primers and backing rod as standard.
Construction in a London area such as Maida Vale means working on constrained sites: limited storage, booked deliveries and access shared with other trades. We fit around the programme, sealing each elevation or floor as other trades hand over.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Common questions from Maida Vale clients
Can you work on a hospital site such as Hospital of St John and St Elizabeth?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is The Quadrant Business Centre, near Maida Vale, within your area?
Yes, sites like The Quadrant Business Centre are within our area, along with the rest of Maida Vale. Send details of the unit and the work through our quote form for a quick quote.
Can staff carry on working while you are here?
Normally, yes. Phased work can be planned so areas stay in use.
How much does the work cost?
There isn’t a price list, because every site is different. Send photographs or drawings and we’ll price it at a fixed figure.
Which sealant do you use on facades?
The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing, and we work to what is specified.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Can you just add new sealant on top?
No. A bead run over old sealant soon lifts. Our method is a full cut-out, cleaning, backing and a new bead.
Facades, frames and programmes in Maida Vale
Maida Vale has a good number of hotels close by, all within 2 miles. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Maida Vale. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
For contractors at a college like City of Westminster College, which lies west of Maida Vale, perimeters and internal sealant are timed for the holidays. On a campus such as Imperial College London, which lies south-east of Maida Vale, new teaching buildings and residences are normally built and refurbished around the academic year. Work at a hotel such as Colonnade Hotel (under half a mile south-east of Maida Vale) tends to be programmed around bookings, mastic included.

Why act early in Maida Vale
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts, often turning up far from the joint. Getting scaffold, permits or access booked in Maida Vale takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

How a job runs
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Planning a London job such as one in Maida Vale starts with access. Give us the hours we can be on site and we will schedule to suit.
- First we review photos, 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.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- 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.
- The completed runs are checked with you, then the 12-month guarantee applies.
Getting the site ready
- Send asbestos survey details if the building is pre-2000
- Confirm the product named in the specification
- Tell us which areas need to stay in use

What else we do in Maida Vale
Different surfaces, different methods
Render and coated surfaces
Where the joint will be painted over, a paintable hybrid or PU sealant may suit. The choice depends on the specification and finish.
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.
Quoting for work in Maida Vale
What shapes the price:
- Travel to remote or island sites
- Whether the work must be split into stages
- Removal of failed or old sealant
- Site requirements such as inductions and permits
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
What to include in your enquiry
To price the job accurately, we need to understand the site. Send us:
- Clear photographs of the problem areas
- What the building is and how it’s used
- Rough lengths or quantities, or drawings if you have them
- Your programme or deadline
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.
Site staff or a sealant specialist?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
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.
Looking after the joints
Regular inspection catches problems early. In particular:
- Keep pressure washers away from fresh sealant
- Confirm the survey covers external sealants in older buildings
- Report water ingress at frames as soon as it shows
- Keep sills, gutters and drainage paths clear
Keep gutters, sills and drainage paths clear. Good drainage keeps water moving off the facade instead of soaking the joints.
Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.
