Quick Answer
The five highest-return paver maintenance tasks for a Roslindale backyard are: pressure-wash at 2,000 PSI in mid-August, replenish polymeric joint sand on visibly washed-out joints, reset settled edge pavers before fall freeze-thaw, seal every 2–3 years, and clear weeds from joints monthly. A 250 sq ft patio takes about 4 hours of DIY work and runs $120–$200 in materials.
1. Pressure-Wash at 2,000 PSI in Mid-August
By mid-August, Roslindale paver patios have collected a season of pollen, summer storm sediment, and BBQ grease. Pressure-washing at 2,000 PSI with a 25° fan tip lifts the grime without damaging paver surface or blowing joint sand out of intact joints.
Hold the nozzle 12" off the surface, work in 3-foot strips with overlapping passes. A 250 sq ft patio takes 60–90 minutes.
If your washer goes higher than 2,500 PSI, dial it down or use the wider 40° fan tip. Excessive pressure strips paver color.
2. Replenish Polymeric Joint Sand
Walk the patio after washing. Joints lower than ⅛" below paver top need re-sanding. Sweep dry polymeric sand into the joints, vibrate with a stiff broom, then water lightly per product directions to activate the binder.
For a 250 sq ft patio with 3/16" joints, plan on 0.05 cubic yards of Mason Sand for tight joints or polymeric for wider. Browse the Patio & Walkway Base collection for current pricing and the Roslindale Landscape Supply page for delivery scheduling.

3. Reset Settled Edge Pavers Before Fall Freeze-Thaw
Freeze-thaw cycles in Roslindale's clay-heavy soils heave edge pavers more than interior ones. Walk the perimeter — any paver sitting more than ¼" below grade or rocking when you press it needs resetting.
The fix: 1. Pry the paver out. 2. Top off the bedding sand with Mason Sand to bring the bed to grade. 3. Reset the paver, tap level with a rubber mallet. 4. Re-sand the joints.
A Roslindale patio with 6–10 settled edge pavers runs about 90 minutes of DIY work.
4. Seal Every 2–3 Years
Sealing protects paver color from UV fade and prevents oil and food stains from penetrating. Apply with low-pressure sprayer, back-roll, second coat after 30 minutes.
Sealing window for Roslindale: late August through mid-September. Pavers must be fully dry, surface temp 60–85°F, no rain forecast within 24 hours.

5. Clear Weeds from Joints Monthly
Weeds in paver joints are a sign of low joint sand. Pull weeds by hand monthly during the growing season. After clearing weeds, top off the joint sand to prevent re-emergence.
Skip chemical weed killers in joints — runoff lands in beds and storm drains, and several common products damage paver bedding sand.
