Construction mastic in Lissenden Gardens
Most of the packages we price run well beyond frames: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. One contractor for all of it keeps the responsibility in one place. We work on sanitary and kitchen joints, internal decorators’ caulk and floor and skirting junctions, and the usual reasons a site gets in touch are frame gaps too wide for sealant alone and early adhesion failures on new external joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Lissenden Gardens it comes down to the same thing: the right product in a properly prepared joint.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Lissenden Gardens must meet its standards or pay the daily charge. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
Our 12-month guarantee is about workmanship, not 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.

Why act early in Lissenden Gardens
It helps to bring the mastic subcontractor in before the package is urgent. Early involvement means gaps, products and access are sorted before the programme bites, which avoids last-minute problems. Leave it late and they turn up on the snag list. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

When it isn’t the sealant
Being straight saves everyone time. New sealant won’t cure:
- Frames fitted out of tolerance
- Approving fire stopping as compliant
- Joints damaged after sign-off by following trades

What we are called out for in Lissenden Gardens
Dust is the enemy of adhesion on a construction site. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.
Most enquiries start with something like this:
- External joints sealed in damp or cold conditions that are now failing
- Missed perimeter joints on a new elevation
- A mastic package split between trades with no clear owner
- Perimeter gaps outside the sealant’s range
Building work at universities like American University in London, 1.5 miles east of Lissenden Gardens, is often timed for the summer, mastic included.

FAQs: Lissenden Gardens

Will you take on work at estates like Regis Road Business Park, close to Lissenden Gardens?
Yes, sites like Regis Road Business Park are within our area, along with the rest of Lissenden Gardens. A few photographs and the unit address let us price the work.
Can staff carry on working while you’re here?
In most cases, yes. Phased work can be planned so areas stay in use.
What hours do you work?
We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
Can you follow the specification on our project?

How do you work with the site programme?
The programme sets the job. Tell us the sequence and we will plan applicators around it so sealing follows the trades.
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.

Different surfaces, different methods
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. We use the specified perimeter sealant, normally a low-modulus neutral-cure silicone.
Snagging before handover
Snags typically come from damage by following trades, missed joints or poor earlier work. Snagging can be included or priced separately.
From enquiry to sign-off
We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you. In Lissenden Gardens, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- First we look at the scope on site or from drawings.

- Paperwork is agreed and applicators are inducted on site.
