Planned Glazing Maintenance & PPM
Reactive glazing spend is expensive and unpredictable. Planned maintenance turns the same money into a known annual figure and a facade that stops surprising you.
A PPM visit is a systematic service of the glazed envelope: seals and gaskets checked and renewed where perished, drainage cleared, ironmongery and restrictors adjusted and lubricated, fixings checked, and any developing defect logged with photographs and a priority rating.
You receive a condition report after each visit with a costed schedule of recommended works, so the following year's budget is based on evidence rather than guesswork. Multi-site portfolios are handled to a single reporting standard.
Repeat work on live venues benefits from the same evidence trail: ARRT has delivered multiple projects over 10 years at Alexandra Palace, a Grade II listed London landmark (Grade II), from external roof sealing to glass unit replacement at height.
Why plan glazing maintenance?
Glazed roofs, atria and curtain walling rarely fail all at once. Sealant joints perish, gaskets shrink or slip, drainage channels block and ironmongery seizes, and each small defect becomes a leak or a failed unit when the weather turns. Reactive call-outs then arrive at the worst time and at the highest cost. A planned programme finds those defects while they are still small, and lets you schedule the work around the building rather than around the weather.
From one-off repair to a planned programme
Many PPM programmes start after a glass roof leak repair, a glass leak repair or an emergency make-safe. Once the immediate problem is fixed, we can survey the rest of the glazed envelope at the same time and propose a visit pattern based on exposure and how critical each asset is. The aim is simple: the next problem is found on a planned visit, not by a call from the building.
Access that suits the building
We service glazing by rope access, MEWP, cradle and internal access, chosen for the building and the scope. Rope access is carried out by IRATA-trained technicians, alongside IPAF and PASMA trained operatives and CSCS-carded site teams, with £10 million public liability cover. Where a survey or inspection is needed first, it feeds straight into the maintenance schedule.

Questions we get asked
What does a PPM visit actually include?
A defined, repeatable scope agreed with you up front — typically seal and gasket inspection, drainage clearing, ironmongery servicing, fixing checks and a written condition report with photographs.
Can you take on a portfolio of buildings?
Yes. Multi-site clients get a single reporting format, one point of contact and a consolidated annual programme.
Can you set up PPM after a leak repair or make-safe?
Yes. Once the immediate problem is fixed, we can survey the rest of the glazed envelope and propose a planned programme, so further defects are found on a scheduled visit rather than as an emergency.
How often should glazing be serviced?
It depends on exposure and how critical the asset is. Annual, bi-annual or quarterly visits are typical, and we agree the pattern with you after the first survey.
