We are your one-stop cleaning and maintenance specialists for all your building needs.


Caulking and Weatherproofing:  Whether your building is a high-rise or low-rise, caulking and weatherproofing can effectively help lower energy costs and decrease the risks of water leaks, thus preventing possible water damage to the interior of your property. Our team is fully trained in the application of caulking. It can be applied to any gaps in the structure of a building, and is commonly used around windows.

We use a waterproof commercial sealant, which is durable, high-performance, flexible and fast-curing. The end result never cracks and the sealant will, in fact, expand and contract with the structure over the years to come.

Spider Control and Treatment:  This service is beneficial for buildings that are prone to spider infestations (ie located near the Lake of Ontario or any body of water, near ravines or wooded areas). The most effective way to combat the issue of spider infestations is to spray the exterior of the building (ie precast, around vents and windows, balconies, roof and ground) with chemical that provides effective control when treating spiders, cluster flies, mosquitoes, etc.  It is important to reduce the pest population (ie other insects) that spiders feed on - their food source.  These pest control chemicals are highly-regulated in Canada and are considered to be safe and of low-toxicity.  It is harmless to humans and pets once it dries.

Moreover, our team will routinely inspect and thoroughly clean the building to remove spiders, spider webs, spider eggs and nests from the frames, corners and under metal panes. 

PrimeTech Builidng Services provides outdoor spider control services for businesses of any size - from office / residentatial towers to low-rise buildings.  A unique program can be designed for your building to quickly minimize and/or eliminate even extensive infestations.  Please contact us for more details.


Metal Cleaning:  If you have any metal surfaces that need restoration, protection and cleaning, we have the appropriate tools and equipment. Our crews can remove dust, dirt and debris from exterior metal surfaces. Moreover, our crews are properly trained to clean chalky oxidation and to apply a protective coating that will make your metal surfaces look new again.  Invest in protective coating to restore and protect your exterior metal surfaces from UV rays, acid rain, bird droppings, mildew, as well as protect them long-term from corrosion, oxidation, rust, tarnish and fading, thus avoiding costly repairs and/or metal replacements in the future.

Exterior Building Power Washing:  Our power washing services will remove years of grime, mould and mildew that have built up on the exterior surfaces of your building.  Pressure washing is a fast, efficient and cost-effective way to wash a building’s exterior, and it will result in the look of a real face-lift to your property. Best left to the experts, power washing can result in damage to surfaces if too much pressure is applied.  Rest assured that our workers are fully trained. You’ll be delighted with the results.

Inspection, Cleaning and Replacement of Dryer Vents:  Clogged dryer vents can result in deadly fires or poisonous gas fumes. It is also the reason for longer dryer operating time, which means higher energy costs for the laundry system.  We have the tools and the expertise to reach deep into your dryer vents and clean out all the debris, lint and dirt that has built up along the lining of the ventilation pipes.  We will also replace any cracked and/or damaged vents.

Confined Space Entry and Cleaning of Ventilation Shafts:  In confined spaces, where entry and exit points are limited, there is little room to work. These situations allow for dangerous and stressful work environments for workers. At PrimeTech Building Services, we have the professional training and the right equipment to clean these areas effectively.

Chandelier Cleaning:  No matter how difficult your chandeliers are to access, we will clean them with a special cleaning solution that will bring them back to their original lustre. Whether you have grand entrance chandeliers with thousands of crystals, or modern wall sconces, we can help.

Solar Panel Cleaning:  Solar panels need to be kept constantly clean for good reason. When they start to cloud over with dirt and pollution, it takes them longer to energize and put power on to the grid. Over time they will become less and less effective as they become cloudier.

We use a chemical-free solution that simply removes the dirt without compromising the efficiency of the panels. Our workers are fully trained in this regard, and they will also notify you if they notice any defects or damage to the panels.
