Your Comfortable, Long Lasting and Efficient House: Long Island Building Science Home Improvements Contractor


At Topnotch Construction, the principles of building science and the holistic “Whole House” approach apply to every project we undertake. When your home is opened up for remodeling it is the perfect time to address comfort and efficiency.

Building Science

Building Science is the application of scientific principles toward a structure to help achieve the following:

Durability: Buildings should last for many years. Properly designed and performing structures often last for 100 years or more.

Moisture Management: Moisture is the enemy of a building. Moisture can permeate building components and lead to rot, insect infestation, mold, mildew and premature failure.

Energy efficiency: Modern buildings are designed to maximize energy usage and reduce consumption. Older buildings can be retrofitted to achieve energy efficiency.

Indoor air quality: As buildings become more energy efficient, the potential for indoor air quality issues increases. Mold, mildew, carbon monoxide, radon and VOCs are all problems that must be prevented.

Thermal Comfort: Building occupants should feel "cozy.” High or low humidity, large temperature swings, cold floors or uneven temperature distribution all lead to uncomfortable conditions for a building’s occupants.
