ICF Home Builders Serving Maryland and Delaware

Some of the finest homes you will see are being built right here by our custom home builders using Insulated Concrete Forms (ICF). Our homes built with ICF offer benefits unmatched by older building materials and few ICF builders are as experienced at constructing them as our team.

The Finest Homes by the Most-Respected Team

Insulated Concrete Form homes are some of the most luxurious to own, and you can talk to us about having one of your own in Maryland or Delaware.

The structure of the concrete allows for a complete range of benefits that a wood-frame house can’t hope to match. Yet, depending on the variable cost of concrete, ICF blocks can actually be cheaper to build per square foot than those same residential homes built from wood.

You want experts to handle the ICF construction of your home, and the professionals at Excel Builders represent some of the most experienced ICF building system experts in the area. We’re happy to help you in large areas of both states, so call today. We can build homes on almost any design, and that home will come with some amazing benefits, like…

Legendary Temperature Stability

ICF blocks as exterior walls provide such great natural insulation that the temperature is typically stable throughout the entire structure. You’ll notice no hot or cold spots as you move from room to room, and it can take hours for an ICF home to lose heating and cooling.

An Unassailable Investment

Traditional homes are vulnerable to a massive range of natural disasters. ICFs hold their own—against high wind, water, insects, and much more. You can be sure that an ICF home will be around for years to come.

A Canvas for Your Imagination

Concrete can be shaped in a variety of exciting ways. Our experienced team has the talent to use this high-quality material to bring your most interesting designs to life. Create interesting slopes and curves in your walls or roof. Tell us about your custom plans today.

Energy Efficiency by the Numbers

It isn’t just about comfort, it’s about value. ICF owners typically pay only a fraction of the heating and cooling costs paid by owners of stick-built homes.

Care to see proof? Here, you’ll find numbers from one of our most recently-built ICF homes that is 3,364 square feet. You’ll note that these amazing savings come with our personal guarantee.

Case Study

Interested in more hard data about the power of insulated concrete forms? No one would know better than Energywise. We work with EnergyWise to develop the energy-saving estimates we use for our guarantees. They’ve found that you can expect the following savings from insulated concrete forms:

The average 3000 sq. ft. home has a monthly energy bill of $300 per month. An ICF house of around the same size, however, uses energy that costs an average of only $90 per month. That means a total energy cost savings of $210 per month.

Even if you assume that your ICF home construction cost will add $10,000 more to your build (it could possibly cost less!) and even with a 7.25% interest rate, that only means an additional cost of $60 per month for choosing ICF. That’s still an extra $60 a month in your pocket from the point your home is built!

Stands winds up to 250mph ICF Homes

Unmatched Durability

ICF homes can withstand winds of up to 250 miles per hour. A full-blown hurricane starts with wind speeds of only 75 mph, and you are protected at speeds of up to 250 mph. Take a look at this ICF built Hurricane Katrina home which is the ONLY ONE left standing in the whole neighborhood: Katrina ICF Home.

ICF custom Homes Mold Resistance

Superior Resistance to Mold and Pests

Black mold is associated with many different health problems. Even beyond health risks, it’s an expensive and labor-intensive problem to fix. ICF custom homes are not only mold-resistant but nearly mold-proof! The material is not a good home for mold, and unlike some house materials, mold cannot consume it for nourishment.

ICF-built Houses Fire Resistance

Reassuring Fire Resistance

ICF-built houses are extremely fire retardant. Naturally, concrete is not flammable. Multiple studies have been performed on the behavior of ICF in a fire. Those studies found that ICF frames took 4 times longer to show any structural damage than wood-frames in the event of a fire.

ICF concrete Sound Isolation

Natural Sound Insulation

Sturdy ICF concrete is remarkably sound-proofed. Even with busy streets outside and airplanes overhead, you’ll have a home that remains quiet and peaceful. Studies have found that these concrete homes insulate 4x more noise than lumber-based homes. Your house will always be your oasis.

FAQs for ICF Builders

Does ICF Home Building Cost more than Traditionally-built Homes?

The cost of ICF homes may not be higher than traditionally-built home. ICF cost per square foot comes down to many factors. While all custom homes are likely to cost more than existing homes with the same square-footage and features, there are also some factors that may make ICF homes more affordable. For example, the cost of ICF homes depends on the going market rate of concrete. There are periods when, due to supply, the cost of concrete may be lower than other popular materials. Additionally, you may save on the cost of a home overall because you won’t be charged for features that you don’t want to use.

What Advantages/Problems Do ICF Homes Have Over Traditionally Built Homes?

ICF homes enjoy a significant number of advantages over traditionally-built homes and some features that can be considered ICF home problems depending on need. In the information in the upper sections of this page, you can learn how: ICF home building is more resistant to wear from age, strong winds, insects, mold, and other common threats to the home. ICF homes are naturally fire-resistant because the materials are not flammable ICF homes are more energy-efficient because they naturally trap heat and cold. ICF homes filter more outside noise, leading to superior sound insulation.

Are ICF Homes Protected by a Warranty?

Our ICF homes are protected by a warranty. We offer a comprehensive warranty that covers materials and construction quality. You may not be able to receive a warranty of the same quality if you choose a different ICF home builder for your ICF home.

Do ICF Homes Last Longer than Traditionally-Built Homes?

ICF Homes have a significantly longer natural lifespan than traditionally-built homes due to the long natural lifespan of concrete forms compared to wood. Concrete forms should last a century with basic maintenance. Many forms of maintenance that are necessary to preserve timber—such as sealing and termite control—are not necessary with concrete forms.

Can you Install Fixtures into ICF walls?

Yes, all types of standard fixtures can be installed into concrete walls. It is wise to plan electrical and plumbing fixtures in advance so that their paths can be built directly into the concrete. This is a simple process that also allows them to be effectively hidden from view when they are not receiving maintenance. Other fixtures, such as wall hangers, can be installed using web points that are located across the frame. Many different kinds of backing can be installed between the concrete and interior to allow you to screw in items without drilling into the concrete.

What are Insulated Concrete Forms?

Insulating Concrete Forms (ICFs) are high-performance concrete walls that are cast-in-place between two layers of insulation material. The insulating layers are constructed to match the planned frame of the building, and then concrete is poured between the layers to form the exterior walls and complete the ICF system. Rebar may be used to further reinforce the forms at points along the wall system.

Siding can be applied to the exterior walls to create an identical exterior to other types of construction. Drywall, Stucco, or other materials can be attached to the interior walls to create the same effect indoors.

What are the thermal benefits of ICF?

ICFs provide exceptional thermal insulation that blocks outside heat and cold while preserving indoor temperatures for extended periods of time. This results in stable temperatures and less strain on indoor HVAC systems.

The performance of ICF is due to the material’s thermal mass that is capable of achieving R-value scores of 22 or better. R-value is a measure of the thermal resistance of an insulating material, where a higher number represents greater effectiveness to resist heat flow. Competing home construction materials like wood possesses R-value scores between .70 and 1.41.
