Ottawa Building Services FAQs

Why should I get my windows cleaned by professionals?

Getting your windows professionally cleaned is the safest and most efficient way to ensure your windows will be properly maintained for long-term use. Professional window cleaners have access to advanced tools, techniques, and cleaning solutions that can help identify and address any potential issues before they become a problem. Additionally, professional window cleaners are highly trained in safety protocols which ensures that all work is conducted in a safe manner away from potential hazards.

A key benefit of getting your windows professionally cleaned is that it helps maintain the overall appearance of your home or commercial building while making sure the glass has maximum transparency that allows natural light inside. Professional window cleaners also take extra care with any led or stained glass by using specialized products designed specifically for these types of materials.

How often should gutters be cleaned?

Generally, gutters should be cleaned at least twice a year. They need to be inspected and cleaned in the late fall after the leaves have dropped from trees, and again in the early spring before the trees begin to bud. If there are many trees around your home or if you’ve experienced a lot of storms during winter months, it is recommended by professional gutter technicians that you inspect and clean your gutters more often (three times per year).

During each gutter cleaning session, any debris such as pine needles, maple seeds, bird nests, or even dirt must be removed. Your gutters also need to be flushed out with water in order for them to function properly. Additionally, check for rust spots on metal-based systems and make sure that downspouts are free-flowing so water can drain away efficiently. Finally, all fasteners should be checked for proper tightness & sealant around seams should also be looked at since over time this can break down allowing leaks and causing damage inside your home or outside the garden area below.

How often should my roof be cleaned?

It’s recommended to have roof cleaning done at least every six months. This is because your roof accumulates dirt, debris, and other materials over time which can cause expensive damage. Professional cleaning services are skilled in removing any material that could potentially harm or damage the surface of your roof, so it’s important to use a professional service if you want to maintain the integrity of your home’s roofing system. Additionally, regular cleaning will help prevent mold growth and water stains from forming on the tiles or shingles of your roof. Professional services can also check for signs of wear and tear that could lead to larger repair problems down the road.

How do I find the best window washers near me?

Finding the best window washers near me may seem like a daunting task, but it doesn’t have to be! Start with researching professional window washing companies in your area and read reviews from customers. Make sure they are licensed and well-reviewed before making an appointment. Once you’ve found a few that suit your needs, ask them how long they have been in business and what their experience level is with window cleaning. Find out if they offer any special services or discounts for being a repeat customer.

Next, request quotes from each company to compare prices and make sure you read the fine print to understand exactly what is included in the service package. This will help ensure you are getting all of the services that fit your needs at an affordable price point. Finally, once you’ve chosen a window washer, set up a meeting or phone call to get more information about their process so that you can feel confident with your decision. Keep track of when they give quotes and other deadlines as part of good communication between yourself and the company. They should also take steps to ensure safety during their work (such as following proper ladder technique) so that no one gets hurt while cleaning windows!

Why should I get my gutters cleaned by professionals?

Getting your gutters cleaned by professionals is an important part of maintaining the health of your home and protecting its value. Regularly cleaning your gutters can help prevent water damage, reduce ice dams and icicles, eliminate pest problems, and stop mold or rot from developing in the roof structure or attic.

When you hire a professional to clean your gutters, they’ll be able to identify any issues with the system such as blocked downspouts or missing hangers so they can be taken care of right away. They also have access to commercial-grade tools like blowers and vacuums which are far superior to anything you may find on the market for basic use at home. This ensures that more debris is collected along with any sediment that may have built up over time so you don’t wind up with clogged drains due to a buildup of debris restricting water flow. With regular cleaning by professionals, you’ll also have peace of mind knowing that nothing will slip through the cracks since they take special care when using ladders around both gutter systems and roofs as well as ensuring all safety protocols are followed for every job site.

What is soft washing and how is it different than pressure washing?

Soft washing is a professional cleaning technique that uses low-pressure water and specialized biodegradable detergents to safely and effectively remove surface dirt, grime, algae, fungus, lichen, moss, and other contaminants from exterior surfaces. Unlike pressure washing which utilizes high-pressure water jets to literally blast away debris from hard surfaces, soft washing relies on the chemistry of the detergent to dissolve or suspend dirt until it can be rinsed away with relatively low pressure. This makes soft washing an ideal choice for residential homes because it does not damage fragile siding materials like paint or wood.

Is soft wash house cleaning effective for cleaning my house?

Yes, soft wash house cleaning is an effective way to keep your house clean. Professional cleaning companies use this type of system to provide a more thorough cleaning than other methods, such as pressure washing or steam cleaning. Soft wash house cleaning uses a low-pressure application of specially mixed detergents and biocides that work together to safely remove dirt, dust, and debris from the exterior of your home. The low pressure allows for precision surface cleaning that minimizes potential damage from high-pressure systems while still providing enough force needed to remove deep grime and debris buildup.

What is the difference between pressure and power washing?

Pressure and power washing are two effective methods of cleaning that can accomplish similar tasks but also have distinct differences.

Pressure washing uses pressurized water to blast away dirt, grime, and other debris from surfaces. This type of cleaning is commonly used on sidewalks, driveways, siding, decks and patios. The process involves a pressure washer machine connected to a hose with an adjustable nozzle to direct the water spray at various angles. The intensity of the jet stream can be adjusted depending on the type of surface being washed as well as the dirt or debris being removed.

Power washing differs from pressure washing in that it utilizes heated water instead of just cold or lukewarm water during the process. Power washers use either gas-powered engines or electric motors to heat up the pressurized jets up to 200 degrees Fahrenheit for more intense cleaning capabilities than what is possible with a standard pressure washer alone.

What are the advantages of hiring residential window cleaners?

Hiring residential window cleaners can provide a number of advantages that DIY cleaning simply cannot.

First and foremost, professional window cleaners are trained in the proper techniques for cleaning windows without damage and with maximum efficiency. This means that your windows will look their best with fewer streaks and smears than you would get from using over-the-counter solutions. Not only is this aesthetically pleasing, but it also increases the lifespan of your windows by ensuring proper maintenance. Additionally, commercial window cleaners use specialized tools not available to home users which can optimize the cleanliness of your windows substantially more effectively than manual scrubbing or spraying methods.
