Colorado homeowner's guide

Keep a Colorado house sound, season by season

Hail in June, a sprinkler that has to be empty by October, ice at the eaves in January and radon under the slab all year. Plain guidance on what to check, when, and how to hire the right help when you need it.

The almanac

What a Colorado house needs this month

Pick a month. Each list is built around Front Range weather: freeze dates, hail weeks, March snow and dry winter air. Tick tasks off as you go; your progress stays on this device.

      Why it is different here

      Five things Colorado does to a house

      A maintenance checklist written for Ohio or Georgia misses most of what wears a Colorado home down. These are the forces worth planning around.

      Hail

      The Front Range sees frequent hailstorms in late spring and summer. Damage is often invisible from the yard, so habits and documentation matter more than luck.

      Hail and roof checks

      Freeze and thaw

      Sunny days above freezing followed by hard nights cycle water in and out of ice all winter. That is how ice dams form and how small cracks grow.

      High-altitude sun

      Thinner air lets more ultraviolet through, which breaks down paint, stain, caulk and roofing faster on south and west exposures.

      Seasonal calendar

      Dry air, short watering season

      Irrigation runs for a few warm months, then every line has to be emptied before the ground freezes. Backflow preventers sit above ground and freeze first.

      Radon

      Colorado geology makes elevated radon common. You cannot see or smell it, and the only way to know your home's level is to test.

      Before you sign

      Most bad projects go wrong at the bid stage

      After a hailstorm, flyers and door knockers arrive within days. A little structure in how you compare contractors protects you from the worst of it.

      1. Check what your city or county requires for licensing and permits.
      2. Get the scope, materials and schedule in writing, on every bid.
      3. Confirm insurance with the carrier, not just a certificate.
      4. Never pay most of the job up front.
