Busy weeks turn into busy months. In Texas, that often means missed exterior chores—caulking, gutter cleaning, chimney checks—that quietly create leaks, wood rot, and mold. Local seasonal guides for Texas call out these exact tasks because our weather swings expose lapses fast. 

Why these small tasks matter

• Gutters = first line of defense. When gutters or downspouts clog, water spills behind siding and toward the foundation. IBHS’s severe-weather prep guides explicitly say to clear and secure gutters/downspouts and seal exterior gaps to reduce storm damage. 
• Caulk keeps water and hot air out. DOE’s Energy Saver notes caulking and weatherstripping cut energy costs and improve durability—quick, high-ROI work that also blocks water at joints and trim. 
• Chimneys need annual eyes on them. NFPA 211 (via CSIA) recommends annual chimney inspections; soot, cracked crowns, or bad flashing can channel water straight inside. 

A seasonal plan for Texas exteriors 

Here’s a checklist of maintenance tasks you should do every season:

Spring (before storm season)

• Clean and flush gutters/downspouts; re-secure any sagging sections.
• Re-caulk cracked joints at windows/doors, trim, and penetrations; replace brittle weatherstripping.
• Inspect roof-to-wall kick-out flashing and chimney flashing; fix stains or gaps now.
• Walk the roofline from the ground after rains; look for creased/missing shingles and dented vents.
• Start up irrigation: fix leaks/broken heads, aim sprinklers away from the foundation, and set reasonable runtimes.
• Extend downspouts 5–10 ft; add splash blocks or drains where grade is tight.
• Service A/C early: replace filters, clear the condensate line, clear vegetation 2–3 ft around the condenser.

Summer (heat + UV)

• Check south/west walls for peeling paint or split trim; spot-prime and seal.
• Trim branches over the roof and near windows to reduce wind damage.
• Wash exterior, then re-caulk sun-baked seams that opened.
• Inspect siding for warping/gaps; seal penetrations (cable, hose bibs) against pests and water.
• Flush the A/C condensate line again mid-season; confirm drain pan sensor works.
• Inspect decks/rails; tighten fasteners and re-seal high-sun surfaces if needed.
• Monitor foundation perimeter moisture during drought (even, low-and-slow watering to avoid shrinkage cracks).

Fall (before fronts and holidays)

• Clear gutters again after leaves drop; verify downspouts discharge well away from the slab.
• Schedule chimney inspection (sweep if needed) before first fire.
• Seal small masonry and siding cracks to keep wind-driven rain out.
• Prune trees back from roof and service drops; remove dead limbs.
• Service heating equipment; test smoke/CO alarms and replace batteries.
• Drain/flush water heater sediment; inspect T&P discharge piping.
• Touch up exterior paint at exposed trim and fascia; reseal driveway and walkway cracks.

Winter (short days, quick checks)

• After hard rain, walk interior perimeters for new stains or musty spots; trace to flashing/gutter issues.
• Touch up failed caulk; replace door sweeps that drag or leak air.
• If you skipped fall chimney work, book it now.
• Freeze protection: disconnect hoses, cover hose bibs, and drip faucets during hard freezes; open sink-base cabinets.
• Check attic and around penetrations after fronts for fresh leaks or condensation; address quickly to avoid mold.
• Clean dryer vent outlet and check exterior GFCIs; replace cracked in-use covers.

What to DIY vs. hire

Reasonable DIY

• Gutter cleanouts from the ground or a safe ladder; downspout flushes
• Caulking small gaps at trim, siding joints, and window/door casings (follow product label) 

Call a pro

• Persistent gutter overflow with clean channels (undersized or mis-pitched system)
• Missing/failed kick-out, step, or chimney flashing
• Interior stains or mold after storms; chimney masonry or cap issues (book a CSIA/NFPA-aware sweep) 

When to call someone now

• Active leaks, soft drywall/trim, or recurring ceiling stains
• Visible gap where a roof slope meets a wall (likely missing kick-out)
• Sooty, cracked, or rust-stained chimney components; smoke backup; musty odors after rain

Bottom line

In Texas, skipping small exterior jobs turns into water and mold problems fast. Clean gutters, seal gaps, and inspect chimneys on a seasonal rhythm. Track it in TradeCrews Property Journal and run a Jack Report™ each season—so you know what’s next and your contractor prices the job accurately.
