Quality Comes First in Window Installation

Whether you are looking to upgrade your current home with replacement windows or you are looking for new windows for a brand-new home, it is important that you have a window replacement company that prides itself on its quality of work. Quality is everything if you want your windows to deliver the energy savings and performance you desire for your home.

 

Poorly-manufactured and installed windows will not save you any money in heating or cooling costs. Even if you purchase our highest-quality windows, if they are not installed properly, you could run into some issues down the road. Our window replacement experts will not disappoint, as they have installed many windows over the years. Our customers are our most valuable assets, and we want to make sure that our windows are installed correctly the first time. 

Types Of Windows

Window Installation and replacement is our specialty! Whether you are looking to replace old and tired paned windows, vinyl windows, wood windows, casement windows, fiberglass windows, or aluminum windows, our professional installation techniques will have you covered no matter the type of window. 

 

Double Hung Windows

Double-hung windows are a type of window that is made up of two sashes, one above the other. These windows are usually installed in pairs or groups with each sash opening to the opposite side. They are an excellent choice for many reasons including their ability to provide great ventilation and light control. Double-hung windows also offer plenty of design options that can suit any home decor style, personality, or budget.

Double-hung windows have been around since the early 1800s but it wasn’t until after World War II that they became popular due to the increasing demand for energy-efficient buildings. Today they are still widely used because they meet LEED requirements and look great on almost all homes!

Vinyl Windows

Vinyl windows are a type of window that is made out of vinyl, which is a soft and flexible plastic. It can be easily molded into various shapes and used to make many different types of products. There are many reasons for this choice in materials – including the fact that vinyl is strong but also lightweight, easy to work with, inexpensive, long-lasting, and durable. However, it is also not as easy to recycle; but new vinyl windows are manufactured with 95% recyclable materials. They are also more efficient than most other windows, due to their low emissivity.

Vinyl windows are usually preferred to aluminum or fiberglass-clad wood because it is easier to work with and more durable than both of these materials. Vinyl is also often less expensive than other types of windows, but this depends on the specific type of vinyl window that is being purchased. When the vinyl window has better insulation and energy-efficient features, it can also be more expensive.

Wood Windows

Wood windows have been in use for hundreds of years. In fact, the very first window ever seen on a church was made from wood. Wood was chosen because it is flexible and can be easily cut into different shapes.

Wooden windows generally come with three panes: one large pane that acts as a vent and two smaller panes that act as insulation — this type of window is called a ‘ventilating sash’. The larger pane sits between the two smaller ones and slides up or down to let air flow through the building while still protecting it from rain and other forms of water damage.

Replacement Doors

We take our door installations as seriously as our window installations. We have years of experience installing sliding glass doors and French doors and have the expertise and knowledge to ensure that your door replacement project protects your family and enhances the value of your home.

Patio & French Doors

Do you have an old and non-functioning patio door? Are you thinking of upgrading to a French Door? We specialize in the installation process for sliding doors and French doors. Whether you are looking to replace that old sliding patio door or upgrade to something more stylish like a Beautiful French Door, we have you covered. Our craftsman installers take the time to take what we like to call a Critical Measure to ensure accurate measurements when ordering your custom-fitted door.

Storm Doors

Your front door and storm door are the focal point of your home, they are the doors that take the most abuse and most use. At Big Box stores in Northern Colorado, they carry low-quality construction-grade doors. They also like to hide pricing. The price you see on the floor is the base price, add in all the delivery, measure fee, warranty, hardware, and anything else you may need, and that low price tag became much higher in a hurry.

Energy Efficiency

You could save money on energy bills just by installing energy-efficient windows and doors, increasing your home’s value, and reducing your carbon footprint on the environment.

Our Process

Our installation prices are the lowest in the Fort Collins area, so you will be able to recoup your investment quickly. In today’s housing market, homeowners want to get as much out of their home as possible, especially if they are looking to trade it in for a new home with state-of-the-art doors and windows.

Our experts will not only measure your windows, but they will also provide the technical data of sunlight blocking qualities of the glass for you to choose from that will be placed inside your new windows. Our team will help you find a balance between protection from the sun’s harmful UV rays and having the right amount of sunlight to brighten your living space.

I chose Allguard because they offer multiple products and Brian does not hard sell any one product. He listens to your needs and recommends options to you. Pricing was fair and installation service was exceptional. The experience with him was perfect. Highly recommend.

We had a few different bids on our windows. Brian gave us the best impression about the quality of installation and materials, plus our dog liked him. He's a good person and wants the best for his customers.His crew are good guys that I was comfortable letting into my home. They were quick to answer any questions that I had and improved upon the existing structure of the window framing all with a positive attitude.We had five windows installed in a day. Three windows weren't easy to access. They left my house and yard as clean as they found it. They make a good team.Whenever any of my friends are in the market for new windows, I'll be pointing them in this direction. We'll be giving them a call when we replace the rest of our windows as well.

All Guard replaced a three panel sliding glass patio door on our balcony on the fifth floor via a lift plus a second double patio door as well as a huge window. Stain color matched to existing trim, cleanup was professionally provided, every detail was professionally guided and managed by Brian personally. We recommend him highly!

Brian and his team are outstanding. As a real estate professional I can honestly say this is one of the best experiences I’ve had with a contractor in a long time! If you are looking to get a window or door replaced in your house you must use them they are by far the best in Northern Colorado.

Tremendous! Amazing! Spectacular! Second to none!Brian and his crew at AllGuard were everything I was searching for in a company to replace my original 1994 windows and doors. I called 3 companies for estimates and felt the most comfortable when talking with Brian from AllGuard. He wasn’t pushy and actually listened to and addressed my (many) questions and concerns. He was in constant communication throughout the process and quickly responded to (more) questions that came up.Installation day went just as smooth. The crew showed up when they said they would, were courteous, efficient and clean!The windows and doors look and operate great! After the installation was complete, they had a professional cleaning crew come by and tidy up around the work areas! How cool is that!?Simple put, AllGuard exceeded my expectations in every aspect. I would strongly recommend them to anyone looking at window replacement!
