Our Services

From wet basements to shifting foundations, we solve the water and structural issues that threaten old and new homes in Carnegie.

Basement Waterproofing

Wet basements are common in neighborhoods like Library Hill, where spring groundwater rise and poor drainage overwhelm older drainage systems. We install interior systems, seal cracks, and add sump pumps to keep water out year-round.

  • Interior drain board and sump pump installation
  • Foundation crack sealing and wall restoration
  • Humidity control with dehumidifiers and vapor barriers

Foundation Repair & Wall Reinforcement

Cracks, bowing walls, and uneven settlement plague older Forsythe Hill and Irishtown homes built on shifting clay soil. We stabilize foundations with carbon fiber reinforcement, push piers, and wall anchors to prevent collapse.

  • Bowing and cracked wall repair with carbon fiber systems
  • Push piers for foundation settlement and sinking floors
  • Wall anchors to stop outward pressure from soil

Crawl Space Waterproofing & Encapsulation

Crawl spaces under Cubbage Hill and Old Mansfield homes trap moisture, rot wood, and invite mold. We encapsulate with vapor barriers, install drainage, and add dehumidifiers to keep everything dry and safe.

  • Vapor barrier and crawl space encapsulation
  • Interior drainage and sump pump systems
  • Insulation and dehumidification for energy savings

Exterior Waterproofing & Drainage

Prevent water from reaching your foundation in the first place. We excavate around Carnegie homes, apply waterproof membranes, and install French drains to redirect groundwater away from walls.

  • Exterior waterproof membranes and coatings
  • French drain installation and grading correction
  • Landscape restoration after excavation work

Pro Tip: Clay soil in Carnegie expands when wet and shrinks when dry, forcing constant pressure on foundations. Early waterproofing stops expensive foundation repairs later.

Why Local Expertise Matters

Carnegie's unique building stock and hydrology require contractors who know the area.

Older Home Expertise

Craftsman bungalows and American Foursquares in Rosslyn Heights and Library Hill have porous stone foundations and outdated drainage. We know how to protect them without over-engineering.

Clay Soil Solutions

Western Pennsylvania's clay soil shifts seasonally, cracking foundations and overwhelming drainage. Our solutions account for this known pattern instead of treating it as a surprise.

Permit & Contractor Familiarity

We're familiar with Carnegie codes and have relationships with inspectors. Exterior work moves faster because we know local requirements and approval timelines.

Fast Response Time

Emergency flooding or sudden cracks? We're minutes away. For homeowners near Main Street or Chartiers Creek, quick access saves money and prevents mold growth.

Frequently Asked Questions

Do you handle emergency basement flooding in Carnegie?

Yes. We provide 24/7 emergency water removal and drainage assessment. Call immediately to prevent mold and structural damage.

Will interior waterproofing work in older stone basements?

Absolutely. Interior systems are ideal for historic homes where exterior excavation would damage landscaping or neighbors' properties. Interior drain boards and sump pumps work on any foundation type.

What does a foundation inspection include?

We check basement and crawl space walls for cracks, measure wall displacement, test drainage and sump pumps if present, document moisture and mold, and assess soil conditions outside. The full report is yours—free, with no strings attached.

How long does a typical waterproofing project take?

Interior waterproofing typically takes 2–3 days. Exterior work varies based on excavation scope but usually completes in 3–5 days. We'll detail the timeline before starting.

Do you offer financing options for waterproofing work?

Yes. We partner with trusted lenders to make foundation repairs and waterproofing more affordable. Ask about payment plans during your consultation.

How do I know if my foundation is settling or just cracking from age?

Settlement cracks are usually wider, stair-stepped, and appear on multiple walls or in doors/windows that stick. Age cracks are narrower and isolated. Our inspection measures movement and tells you which you have and what to do about it.
