November 7, 2026

This article explains how to maintain a custom home builder project after move-in, especially during the first few years. A new home has systems and finishes that need attention as they settle and age. The schedule below is a general guide, and the warranty from your builder and the manufacturers of your equipment should always take priority in Holmen, WI, and nearby areas. Call (608) 667-0879 to talk through your home's first-year care plan.

Review the Home in the First Year

Many issues appear during the first year as materials settle and seasons change. Walk through the home regularly and note any new cracks, sticking doors, or drafts. Report warranty items promptly so the builder can address them. Keep a written log with dates and photos.


Check the Foundation and Grading

Look for cracks in the foundation, soil that has settled, or water pooling near the home. Confirm that grading still directs water away from the structure. Clear gutters and downspouts so runoff moves away from the foundation. Early attention prevents larger repairs later.


  1. Inspect the foundation for new cracks each season.
  2. Confirm grading slopes away from the home.
  3. Clean gutters and check downspout extensions.
  4. Watch for water stains or moisture in the basement.


Service Heating and Cooling Systems

Heating and cooling equipment works hardest during Wisconsin winters and summers. Change air filters on the schedule recommended by the manufacturer. Schedule professional service for the furnace and air conditioner once a year. Regular service supports efficiency and comfort.


Inspect the Roof, Gutters, and Exterior

Check the roof after severe storms and ice events. Look for missing shingles, damaged flashing, or loose gutters. Inspect exterior caulking and paint on a regular schedule. A well-kept exterior protects the structure from water and wind.


Monitor Plumbing and Electrical Systems

Watch for slow drains, unusual water pressure changes, or flickering lights. Test smoke and carbon monoxide detectors each month. Know where the main water shutoff and electrical panel are located. Call a licensed professional when a problem appears.


Keep Records and Warranty Documents

Store the contract, warranty documents, appliance manuals, and inspection reports in one place. Note the expiration dates for each warranty. These records help you resolve issues quickly. A complete file also helps when you sell the home later.


Plan Seasonal Maintenance

A seasonal checklist keeps maintenance manageable. Spring is a good time to check exterior drainage and the air conditioner. Fall is ideal for furnace service, gutter cleaning, and sealing drafts. Winter checks can focus on ice dams and interior moisture.


Questions to Ask Your Builder After Move-In

Ask which items the warranty covers and how to submit a request. Confirm the recommended maintenance schedule for the systems in your home. Request a list of trusted local service providers if the builder offers one. Clear answers help you protect your investment.


Build a Seasonal Calendar

A seasonal calendar makes first-year care predictable. Spring, summer, fall, and winter each have a few tasks that protect the home. A custom home builder can share a calendar that reflects the systems installed in your home. Mark the dates on your home calendar and keep service receipts with your warranty file. A custom home builder's guidance keeps routine care simple.


Know When to Call a Professional

Some issues should be handled quickly by a licensed professional rather than a do-it-yourself fix. Water in the basement, electrical sparks, gas odors, and sudden changes in heating performance all need prompt attention. A custom home builder can tell you which items are covered by warranty and which should go to a licensed trade. Keep the contact details for trusted providers in your records. Early action often prevents larger repairs and protects your investment.


Create a simple file for each system in the home with its manual, service dates, and warranty details. Include the names of the contractors who installed each system. This record simplifies service calls and helps any future owner understand the home's history. Keep the file in a dry location and make a digital copy as a backup. Organized records make routine maintenance easier and protect the value of your investment over time. Review the file each year to confirm that service dates are current.


Ask your builder which items should be inspected once a year, even when nothing appears to be wrong.


Keep notes on any unusual noises, odors, or moisture as well, since early notes help a technician diagnose problems faster.
