Photos, a specification or a quick description of the joints is enough to start a fixed quote.
What we can’t put right
Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:
- Rework caused by others damaging completed areas
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Frame gaps too wide for sealant, which the installer needs to correct
If you are not sure, just speak to us on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Construction mastic for commercial buildings in Streatham Park
We work to the specification and the programme rather than whatever product is to hand. Where the specification names a product, we use it, and if an alternative is proposed, it goes to you for acceptance first. Backing, primer and depth follow what the sealant maker sets out. Site teams most often ask us about different trades sealing to different standards and window and door perimeters that won’t pass inspection, across cladding and panel joints, internal decorators’ caulk and window and door perimeters. One point of contact handles commercial sealant work in Streatham Park from the first photos to the final walk-round, for single jobs and planned programmes alike.
Construction in a London area such as Streatham Park means working on constrained sites: small compounds, delivery slots and shared hoists and scaffold. 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.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What happens if it’s left?
Clearing snags piecemeal is tempting when handover is close. A planned sweep of each plot or floor catches the lot in one go and saves applicators coming back again and again. We can run snagging as its own phase before handover. In a London building, a failed joint rarely affects only one party. Putting it right early is less disruptive than dealing with the consequences.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

From enquiry to sign-off
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself normally taking as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. In Streatham Park, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised right away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Preparing the site
- Explain the parking and delivery arrangements
- Confirm the product named in the specification
- Agree which areas must stay open

Your questions answered
Can you work at a site such as Mitcham Industrial Estate, by Streatham Park?
Yes. Our area takes in Streatham Park and its surroundings, with estates and business parks such as Mitcham Industrial Estate included. Photos and a short description are enough for a first look.
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, with one point of contact.
Can you seal external joints in wet or cold weather?
External mastic depends on conditions: the joint needs to be dry and within the product’s temperature range. We plan external elevations with that in mind.
Is Streatham Park in your area?
Yes. We cover Streatham Park, and you can phone 01277 525 020 or email the details over to get started.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

How the job changes by surface
Internal decorators’ caulk
Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s for gaps that stay still and get painted.
External facade and movement joints
External movement joints often need primer, depending on the substrate. We prime where the manufacturer specifies and work only when conditions suit.
