Appliance Installation Mistakes to Avoid in Mifflin County Homes

March 31, 2026

Whether you’re upgrading appliances after a kitchen remodel or replacing an old unit that finally stopped working, proper installation matters more than most homeowners realize.  What seems like a simple swap can lead to leaks, electrical problems, damaged cabinets, or voided warranties — especially in older Mifflin County homes with aging wiring and plumbing.  Here are the most common mistakes to avoid and how professional installation can save you time, money, and stress.


1️⃣ Not Measuring the Space Correctly

Today’s appliances are deeper, wider, and more feature-packed than older models.  Even a half-inch difference can prevent an appliance from fitting under counters or into cabinet openings.


Common issues:

  • Door won’t fully open
  • Venting blocked
  • Trim and edges don’t align
  • Scratched cabinets during install


Pro Tip: Always measure width, depth, height and door swing clearance before buying.


2️⃣ Ignoring Electrical Requirements

Many older Lewistown homes weren’t built for modern power-hungry appliances like induction ranges or large refrigerators.


Common electrical issues:

  • Not enough amperage
  • Wrong breaker type
  • No dedicated circuit
  • Overheating wires


3️⃣ Incorrect Water Line or Drain Connections

Dishwashers, refrigerators with ice makers, and laundry appliances rely on tight plumbing connections.  A minor leak can cause mold, subfloor swelling, or cabinet damage — especially over time.


Watch for:

  • Hand-tightened hoses (not enough torque)
  • Missing thread tape
  • Old copper lines that crack under pressure
  • Drain loops installed incorrectly

4️⃣ Poor Venting — Especially for Over-the-Range Microwaves

A microwave "installed" doesn’t mean it's venting properly.  Many installs accidentally vent back into the kitchen, trapping heat, grease, and smoke indoors.


Consider:

  • External roof or wall venting
  • Upgrading duct size
  • Sealing gaps to prevent leaks
  • Ensuring proper alignment with cabinet cutouts


5️⃣ Voiding the Warranty by DIY Installation

Many appliance manufacturers require professional installation for warranty coverage, especially for water or gas-connected units.


Risks of DIY installs:

  • Denied warranty claims
  • Manufacturer support refused
  • Liability for damages shifts to homeowner

Choosing the Right Countertop for Your Kitchen in Mifflin County: Granite vs Quartz vs Marble

December 24, 2025
When it comes to kitchen remodeling, few choices make a bigger impact than your countertops. They’re the visual centerpiece of your kitchen — and one of the most used surfaces in your home. Whether you’re preparing Sunday breakfast in Lewistown or hosting family dinners in Reedsville, the right countertop can blend durability, beauty, and value. Let’s compare three of the most popular options: granite, quartz, and marble — and find out which fits your Mifflin County lifestyle best. 1️⃣ Granite – Natural Strength with Character Granite has long been a homeowner favorite because of its timeless appeal and toughness. Each slab is unique, featuring organic patterns formed deep within the earth. It’s heat-resistant, scratch-resistant, and perfect for busy kitchens. Best for: Families who cook often and love natural stone. Care Tip: Seal once a year to prevent staining. If you would like to coordinate your cabinet and wall colors to match natural stone tones, consult with us on painting . 2️⃣ Quartz – Engineered for Everyday Living Quartz combines style and simplicity. Made from natural stone mixed with resins, it’s nonporous, low maintenance, and available in nearly endless colors. No sealing required — just wipe and go. Best for: Busy households who want elegance without maintenance. Care Tip: Avoid placing hot pans directly on the surface to prevent discoloration. An upscale electric choice would be to add under-cabinet lighting to make quartz sparkle even more. 3️⃣ Marble – Luxurious and Classic Nothing says sophistication like marble. Its soft veining and natural glow give kitchens a timeless look that fits both modern and traditional Mifflin County homes. However, marble does require care — it’s more porous and can etch from acids or wine. Best for: Homeowners who love elegance and don’t mind regular upkeep. Care Tip: Use trivets and clean spills quickly.
