The city of Lafayette is surrounded with tree-covered hills and family-friendly areas such as Happy Valley, and Burton Valley, which is why Lafayette is considered one of the most picturesque cities of the East Bay but, at the same time, moisture and humidity issues are something that homeowners have to deal with in Lafayette. Most of the houses here are located on hilly slopes or clay soils and these two factors contribute to the existence of damp crawl space, insulation damage and loss of energy.
Our company is a professional crawl space repair and encapsulation company within Lafayette. We know the conditions of soil and the weather pattern of a certain season that influences the health of the foundation. Is it the deterioration of insulation, excess humidity, or a low circulation of air that you are talking about? You will have a tailor-made solution that will make your foundation more robust and make your home very comfortable and efficient.
Insulation is important to ensure that your house is comfortable and energy-efficient throughout the year. Inadequate or absent insulation enables heat to pass through the floor, which raises their energy costs and prevents the inside of their homes to get cold spots.
Our crawl space insulation proposals are based on different climatic conditions in Lafayette. We use rigid foam boards through closed-cell spray foam, which will not be affected by moisture and will offer a consistent thermal protection. The correct insulation does not only conserve energy but it also helps to avoid condensation and rotting of wood under your home.
We have the pride of being the preferred crawl space repair and encapsulation company in Lafayette. This is why our team is still favored by the local homeowners:
We are familiar with the terrain, drainage and humidity levels of Lafayette.
Each crawl space will receive its own solution based on its problems.
We will use the best insulation and vapor barrier systems.
You will always have an idea of what we are doing and why it is important.
Our repairs are designed to last and save money.
We are confident in the need to do the job right the first time so that your crawl space can be clean, sealed, and efficient to utilize in the years to come.
Prior to the installation of insulations/vapor barriers, the causative condition behind the damages should be determined. The issues that our team frequently face in Lafayette crawl spaces are as follows:
Persistent Moisture: Poor drainage and rainwater runoff may cause the standing water underneath your house.
Mold Growth and Musty Odors: Mold and mildew thrive in an unsealed crawl space.
Temperature Imbalance: Floors over the crawl space are either cold in winter or hot in summer without insulation.
These issues will be addressed to enable us to have a clean, dry, and energy efficient-platform, which will support long term performance.
One of the best materials in sealing the crawl spaces is spray foam insulation. It seals cracks and holes that conventional insulation is unable to access, creating an air-tight seal around drafts, dust, and moisture.
Open-cell spray foam is not utilized when we build our team because it is not as durable and water-vapor resistant as closed-cell spray foam. It also provides structural strength to joists and walls and ensures that your crawl space remains dry, efficient and safe with the shifting of the seasons of Lafayette.
Our professionals will be able to check, seal and insulate your crawl space in order to avoid moisture issues and enhance performance in all parts of your house.
Arrange your professional inspection of crawl space. We will evaluate your foundation, talk to you about your insulation and vapor barrier alternatives, and provide you a comprehensive plan to keep your Lafayette home dry, healthy and energy saving every season of the year.
We’re here to help! Swiftly addressing these concerns is key. Our experts will promptly inspect and repair your foundation, ensuring the lasting strength and safety of your home. Reach out without hesitation for reliable assistance.
