Your Summer Home Maintenance Checklist: 8 Tasks That Protect Your Home's Value

Why Summer Maintenance Matters

Summer is the busiest season for home wear. Heat, humidity, and daily use stress your home's systems in ways that show up as expensive problems in October and November. A few focused hours in July address most of them before they escalate.

Keeping your home well-maintained also protects its market value. With home values across Greater Boston holding strong, a well-maintained home stands out when it comes time to sell.

Your 8-Item July Checklist

1. Replace HVAC Filters

Your air conditioning system works hardest in July and August. A clogged filter reduces efficiency, raises energy costs, and puts unnecessary strain on the unit. Replace filters now and plan to check again in September. Standard 1-inch filters should be replaced every 60 to 90 days. Thicker media filters last longer — check the manufacturer's recommendation.

2. Inspect Deck Boards and Railings

Wood decks take a beating from spring rain and then summer heat. Walk the deck and press on boards near the ledger and at the posts. Check railing connections. Any soft spots, loose fasteners, or visible rot should be addressed before fall entertaining season. A deck inspection and sealing costs a fraction of what a structural repair runs later.

3. Clean Gutters Before Fall

Most homeowners wait until October. Getting ahead of it in July means working in warm weather, and you catch any damage from spring storms before it causes a leak. While you are up there, check the fascia boards and downspout extensions to make sure water is draining well away from the foundation.

4. Test Smoke and CO Detectors

Replace batteries in all smoke and carbon monoxide detectors. If your smoke detectors are more than 10 years old, or your CO detectors more than 7 years old, replace the units entirely. Massachusetts law requires CO detectors on every level of the home and within 10 feet of every sleeping area.

5. Check Weatherstripping on Doors and Windows

Weatherstripping keeps conditioned air in and summer heat out. On a hot day, run your hand along door frames and window edges. If you feel warm air or see daylight at the edges, the seal is compromised. Replacement kits from a hardware store cost under $20 and take about 30 minutes to install.

6. Inspect the Roof

You do not need to get on the roof. Use binoculars from the yard, or a drone if you have one. Look for lifted, cracked, or missing shingles. Check the flashing around chimneys, skylights, and vents. A small repair now costs far less than a leak that reaches the interior and causes ceiling or insulation damage.

7. Flush the Water Heater

Sediment builds up in the bottom of water heaters over time, reducing efficiency and shortening the unit's lifespan. Attach a garden hose to the drain valve and flush until the water runs clear. This simple step can extend your water heater's life by several years and keeps energy costs down through the winter.

8. Check Outdoor Spigots and Irrigation

Walk your irrigation zones and look for heads that are not rotating, spraying sideways, or missing coverage entirely. Check outdoor hose bibs for drips. Wasted water adds up through August, and a broken irrigation head left running can damage landscaping and create moisture issues at the foundation.
