September and October are the best working months of the year here. The catch is that all five jobs have a hard back edge — frozen ground does not compact, and seed does not root.
Why order material in August for fall work?
Mid-August into mid-September is when cool-season grass establishes here, and that is a four-week runway. Everything else backs up behind it: loam and compost spike with the seed, and base stone runs to the first frost.
What are the five projects?
1. Overseed and topdress the lawn — about 4 yards
The most time-sensitive item. Mow low, dethatch, spread a quarter inch of screened loam, seed into it. A 5,000 square foot lawn at a quarter inch is 3.9 cubic yards, so order 4. Every number here comes off one line: cubic yards = (square feet × depth in inches) ÷ 324.
2. Patio or walkway base — about 4 yards plus 1 of sand
A 12 by 16 foot patio is 192 square feet, and six inches of base is 3.6 yards — order 4 yards of Dense Pack ¾"– plus a yard of paver sand for the setting bed. A base built on frozen or saturated subgrade heaves the first winter. Materials are in patio and walkway base.
3. Drainage before the autumn rain — about 4 yards
Billerica has plenty of flat, wet backyards, particularly on the silty ground toward the Concord and Shawsheen Rivers. A 60-foot trench, a foot wide and 18 inches deep, takes 3.3 yards of #57 stone — order 4. Everything for it is in French drain and drainage.
4. Bed prep for fall trees and shrubs — about 2 yards
Autumn beats spring for woody plants, because roots keep growing in warm soil after the top of the plant shuts down. Amend the bed, not the hole — a 300 square foot bed at two inches of compost is 1.9 yards, so order 2.
5. Mulch refresh before leaf drop — about 7 yards
A two-inch refresh over 1,200 square feet of beds is 7.4 yards. Doing it before leaf drop saves raking mulch out in November, and a fresh layer insulates root zones through the winter freeze-thaw. Mulch caps at 10 yards a trip.
What does each one take?
| Project | Material | Typical order | What sets the deadline |
|---|---|---|---|
| Overseed and topdress | Screened Loam | 4 yd | Seed needs weeks of warm soil |
| Patio base | Dense Pack ¾"– + Paver Sand | 4 yd + 1 yd | Frozen subgrade will not compact |
| French drain | #57 Stone | 4 yd | Autumn rain |
| Planting bed prep | Compost | 2 yd | Roots need time before freeze |
| Mulch refresh | Any bark mulch | 7 yd | Leaf drop |
What does delivery to Billerica cost?
Every Billerica ZIP is inside the flat zone — 18.8 to 25.4 driving miles from our Dispatch Office in Dorchester — so delivery is $100 per load. Loads are counted per line item, so loam, stone and mulch are three trucks and three fees. Stone, sand and soil cap at 6 yards; mulch at 10.

Questions we get in late August
Is it too late to start a patio in September?
No. September and early October are ideal. ICPI covers base construction.
Can I do the lawn and the patio in one order?
You can order both, but they arrive on separate trucks at $100 each, because loads are counted per line item.
How deep should a mulch refresh go?
Two inches over existing mulch, three inches total. Deeper suffocates roots.
What if I do not know my square footage?
Measure beds and lawn separately and subtract anything not planted. UMass Extension's landscape program is a solid reference for the plant side.
