★★★★★"Transformed our property completely" — Lisa R.
Crabgrass, dandelion, clover, plantain, and chickweed all behave differently across the Maine season. Robbins Property Services times pre-emergent and post-emergent applications to the actual growth windows in Cumberland County — not a calendar from another state. Serving Windham, Gorham, Westbrook, Falmouth, Cumberland, Scarborough, Raymond, Standish, Gray, and Portland, Maine.
Step 01
Crabgrass germinates when Maine soil temps hit 55°F — usually mid-April through early May depending on the year. Apply too early and it breaks down before germination; too late and it's already up. We track soil temps locally so the pre-emergent goes down at the right window across Greater Portland.
Step 02
We don't blanket-spray a healthy lawn. Most weed treatments are spot applications on actual problem areas — that means less product on your property, lower cost, and a healthier lawn long-term.
Step 03
For Windham and Falmouth properties with kids, pets, wells, or organic lawn programs, we offer iron-based and other organic-approved spot treatments. Slower acting, but very effective on broadleaf weeds without synthetic herbicide.

Common questions
Mid-April to early May, when soil temps hit ~55°F. We track this locally across Cumberland County and apply at the right window — not a fixed calendar date.
Yes — iron-based and other OMRI-approved options for broadleaf weeds. Great fit for Greater Portland properties with kids, pets, or wells.
Most residential programs run $300–$650 per season for the full pre-emergent + spot-treatment cycle. Bundled with fertilization, the combined program is the best value.
A properly timed pre-emergent prevents the vast majority of crabgrass; broadleaf weeds are spot-treated on each visit. A thick, well-fertilized lawn outcompetes most weeds — so we treat weed control as one piece of the full Maine lawn program.

"Best lawn on the street. Their fertilization program made a real difference in one season. Owner-operated and it shows."
