Fiberglass Well Cover · Insulated · 4 Sizes

This fiberglass well cover pairs a layered fiberglass shell with a closed-cell urethane foam core to protect the wellhead and pressure tank from freeze damage, UV, and the everyday abuse of being out in the yard. The color is a 20-mil pigmented gelcoat molded into the shell, so it never needs painting. It comes in four sizes, from a single wellhead with a compact pump up to larger wellhead, tank, and pump groupings.

Overview

Built to Last. Built to Fit.

This fiberglass well cover is built around a layered fiberglass shell wrapped over a closed-cell urethane foam core, protecting the wellhead and pressure tank from freeze damage, UV, and the everyday abuse of being out in the yard. The 20-mil pigmented gelcoat is integral to the shell and resists the chalking and fading of field-painted units — the color you order is the color that lasts.

Choose from four sizes, from a single wellhead with a compact pump up to larger wellhead, tank, and pump groupings. Snap-tight construction means no fasteners are required for routine service — lift it off, work the well, set it back down. No anchoring hardware is needed for normal use; the shell's weight and shape hold it in place while staying easy to remove for service.

Why Contractors Specify It

Freeze Protection That Holds Up Outdoors

Freeze protection

A closed-cell urethane foam core (~R-7) shields the wellhead and pressure tank through cold snaps from the southern Carolinas to the upper Midwest.

Snap-tight, no fasteners

The cover lifts off and sets back on for routine service — no bolts or hardware to manage in the field.

Gelcoat that lasts

A 20-mil pigmented gelcoat resists UV and weather and never needs painting — stackable for distributor freight efficiency.

FAQ

Common Questions

Why choose a fiberglass well cover?
The layered fiberglass shell carries a 20-mil pigmented gelcoat that is molded in, not painted on, so it resists UV and weather without chalking, fading, or repainting. Inside, a closed-cell urethane foam core (about R-7) adds the freeze protection.
What size fiberglass well cover do I need?
Measure the footprint and height of everything the cover needs to enclose — wellhead, pressure tank, and any pump or backflow components — then add clearance. The Small Standard (18″ L × 18″ W × 22″ H) covers a single wellhead, small pressure tank, or compact pump. The Small-Medium Standard (33″ L × 22″ W × 24″ H) fits a wellhead plus a small tank or dual-line setup. The Medium Standard (40″ L × 35″ W × 38″ H) handles a full wellhead-and-tank install, and the Large Standard (58″ L × 34″ W × 44″ H) covers larger wellhead, tank, and pump groupings.
Does the cover need to be anchored?
For routine installs no fasteners are required; the snap-tight design lifts off for service and sets back down. Anchoring kits can be added where high wind or tampering is a concern.
What casing sizes does it fit?
All four sizes fit 4″ to 12″ casing diameters as standard. Custom configurations are available on request — contact us if your installation falls outside the standard range.
