FAMILY-OWNED IN MATTAWAN • FREE ON-SITE ESTIMATES
Cold floors, drafts or insulation hanging beneath your home? Greenshield evaluates crawlspace insulation, air leaks and visible moisture conditions before recommending the work. We install insulation and ground vapor barriers with a scope suited to your home’s construction.

Missing insulation can contribute to an uncomfortable floor, but it is only one possibility. Gaps around rim joists, poorly supported batts, an unsealed access hatch and unwanted airflow can also affect the rooms above.
Musty odors, damp wood, standing water or fallen insulation deserve attention before new material is installed. We review the accessible space and explain which insulation improvements fit the conditions—and which moisture or repair issues need to be addressed first.
The first decision is where the home’s insulation and air barrier belong. A vented crawlspace and a closed crawlspace need different approaches. Simply adding foam or closing vents does not create a complete system.
When the crawlspace remains outside the home’s conditioned enclosure, insulation may be installed beneath the floor. It needs continuous contact with the subfloor and suitable support, along with air sealing at accessible penetrations.
Ground moisture, ducts, plumbing and ventilation still need consideration. Adding floor insulation alone does not guarantee protection for pipes below it.
A closed crawlspace may place insulation at the foundation walls and rim joists, with a sealed ground vapor barrier. The design also needs an appropriate moisture-management and drying strategy.
Vent changes, combustion appliances, drainage, radon considerations and applicable requirements must be reviewed before converting an existing crawlspace. The written scope should identify work by GSI and any work needed from other trades.
The rim joist runs around the edge of the floor framing above the foundation. Gaps at the sill plate, framing joints and penetrations can allow unwanted airflow into the home.
Where the wood is suitable and accessible, closed-cell spray foam may combine insulation and air sealing at these details. We evaluate surface condition, the planned thickness and any required protective covering. Wet or damaged wood should be assessed before it is concealed.
Closed-cell foam can suit crawlspace walls and rim joists where the assembly and surface conditions allow it. It provides insulation and, at the product’s specified thickness, air control. It does not repair water entry.
A sealed ground liner helps limit moisture vapor rising from exposed soil. Seams, penetrations and connections at walls and supports matter. A liner is not a substitute for fixing standing water or drainage problems.
Rigid board may be appropriate on crawlspace walls. Product selection, attachment, sealed joints and required protective coverings determine how it fits the overall assembly.
Fiberglass batts may suit some vented crawlspaces when properly fitted and supported against the subfloor. Existing moisture and air-leakage problems should be addressed rather than covered with replacement batts.
When existing insulation is wet, damaged or obstructs the planned work, crawlspace insulation removal can be discussed separately. Active pest or water problems need to be addressed as part of the overall repair plan.
Cost depends on crawlspace size, perimeter wall area, clearance, existing insulation, removal needs and the selected materials. A rim-joist project has a different scope from wall insulation with a sealed ground liner.
Your estimate should identify where insulation will go, its thickness or specified insulation level, the vapor-barrier work included and any preparation or protective finish. Ask whether drainage, dehumidification or work by other trades is included or separate.
Greenshield serves Kalamazoo, Portage, Mattawan, Paw Paw, Lawton and nearby Southwest Michigan communities, generally within about 40 miles of Mattawan. We explain the material choices and quote the work for your home’s conditions.

No. Insulation slows heat transfer. Ground vapor control, drainage, leaks and indoor humidity are separate parts of the moisture problem. New insulation should not hide unresolved water entry or damaged framing.
No. Encapsulation typically includes a sealed ground liner and connections at walls, supports and penetrations. Insulation controls heat flow. A complete closed-crawlspace plan also needs an appropriate drying strategy and review of the building’s conditions.
No. We evaluate its condition and whether it fits the proposed assembly. Wet, contaminated, damaged or poorly placed insulation may need removal; suitable material may be retained when it does not interfere with the work.
That depends on the planned crawlspace system. Do not treat vent closure as a stand-alone insulation fix. Ground moisture, drying, equipment and applicable requirements need to be considered together.
No. Closed-cell foam can be useful at rim joists and suitable foundation walls, but material selection depends on the assembly, access and moisture conditions. We explain alternatives when another method fits the space better.
Include the property location, approximate crawlspace size, access opening and any known moisture or insulation problems. Existing photos can help us plan the visit; you do not need to enter an unsafe or inaccessible space to take them.
Tell us about the cold floors, drafts or insulation concerns you want addressed. Include your location and any known access or moisture issues so we can discuss the project and arrange an estimate.
