Commercial Glazing Leak Repair Services

We carry out glazing leak repair and water ingress investigations for facilities managers, building owners, property managers, and main contractors. Our work covers all types of commercial glazing systems, including curtain walling, atriums, rooflights, glass canopies, shopfronts, and commercial windows. Our projects include a full glazing inspection and rectification programme at Pinewood Business Park in Birmingham, carried out to resolve persistent water ingress across a large commercial office estate.

Why should Dynamic Access be your first choice for glazing leak repair?

Our priority is to identify the source of the leak and arrange a targeted repair solution. Ignored or improperly resolved, glazing leaks lead to more expensive problems and greater risks to building occupants’ health and safety.

Our glazing leak repair service begins with an initial site survey, where we assess the defects and access requirements. Water testing is carried out where required to identify the precise source of any leaks and confirm the need for spot repairs or a wider rectification programme. All findings are documented photographically and provided in a written report, giving clients a clear record of the defects identified and the remedial works recommended.

Following the survey, we confirm the replacement or repair of defective components and any system upgrades required.

We have particular experience in carrying out the following glazing leak repairs:

  • Replacing defective silicone weather seals and perimeter sealants.
  • Replacing EPDM gaskets and existing system gasketry.
  • Applying specialist butyl glazing tape where required.
  • Clearing blocked drainage paths, weep routes, and drainage channels.
  • Replacing defective components, including pressure plates, cover caps, and fixings.
  • Adapting and introducing new drainage components to improve long-term system performance.
  • Applying new structural silicone interfaces at glass-to-frame and glass-to-glass joints.

Our expertise extends to hard-to-access areas, allowing us to carry out glazing leak repairs in overhead glazing, atrium glazing, curtain walls, and rooflights, using IRATA rope access where required.

What are the common causes of glazing leaks?

Glazing leaks can occur for a variety of reasons. Age-related deterioration of weather seals, EPDM gaskets, and structural silicone interfaces is among the most common. Blocked drainage paths and weep routes, caused by a build-up of debris and insufficient maintenance, are also a frequent source of water ingress.

Other common glazing leak causes include:

  • Incorrect installation of the original glazing system.
  • Failure of perimeter seals and structural silicone at glass-to-frame or glass-to-glass joints.
  • Defective or deteriorated glazing tape.
  • Failure of system drainage, including blocked or absent weep routes.
  • Damage to glazing system fixings, pressure plates, or capping details.
  • Incorrectly specified previous repairs that failed to address the root cause.

After identifying the cause, we provide a glazing leak rectification service to resolve the issues and remove associated risks. It is worth noting that not all glazing leaks are age-related; many result from incorrect installation or prior repairs carried out to the wrong specification.

What might be the result of failing to carry out overhead glazing leak repairs?

Our recommendation is always to repair glazing leaks at the first opportunity. With correct and timely attention, water ingress can be identified and resolved before it causes wider damage. Leaving a leak unattended risks damage to internal finishes, fixings, and structural elements, and increases health and safety risks for building occupants below.

Over time, an unresolved glazing leak can accelerate deterioration of the surrounding glazing system, increasing the scope and cost of eventual repairs considerably. In overhead and atrium glazing situations in particular, the risks posed by water ingress are elevated due to the position of glazing above occupied areas.

Following completion of glazing leak repairs, we can arrange a glazing maintenance or PPM contract to protect the repaired system and reduce the risk of recurrence. Our maintenance packages include a water ingress guarantee (subject to Ts & Cs).

Glazing Leak Repair FAQs

How do you find the source of a glazing leak?
We begin with a visual survey to identify visible defects in the glazing system. Where the source is not immediately obvious, we carry out water testing to pinpoint the precise point of ingress. This involves the controlled application of water to specific areas of the glazing system while our technicians monitor for internal penetration, identifying even concealed or intermittent leak paths.

What types of glazing systems do you repair leaks in?
We carry out glazing leak repairs across all types of commercial glazing, including curtain walling, atrium glazing, rooflights, glass canopies, shopfronts, and commercial window systems. Our rope access capability means we can access and repair leaks in overhead and high-level glazing where standard access is not possible.

Can you repair glazing leaks at height?
Yes. Our in-house IRATA rope access technicians carry out glazing leak repairs at height, including overhead atriums, curtain wall facades, and rooflights. Access requirements are confirmed at the initial site survey before any works begin.

What is the most common cause of curtain wall leaks?
The most common causes include failed perimeter seals and structural silicone interfaces, blocked drainage paths and weep routes, degraded EPDM gaskets, and defective glass-to-frame joints. Our survey process identifies the specific cause before any repairs are carried out.

Do you provide a guarantee on glazing leak repairs?
Yes. We are one of few commercial glazing contractors to offer an Insurance Backed Guarantee. We also offer glazing maintenance packages that include a water ingress guarantee, providing ongoing protection for clients who want to reduce the risk of recurrence (subject to Ts & Cs).

Can glazing leaks be prevented with regular maintenance?
Yes. Many glazing leaks are caused by the gradual deterioration of seals, gaskets, drainage paths, and fixings, all of which can be identified and resolved through regular maintenance before they develop into active leaks. We offer bespoke glazing maintenance and PPM programmes that include water ingress guarantees.
