Character and charm come standard with older homes, but so do certain structural challenges. One of the most common issues homeowners face in historic properties is uneven flooring. Whether you're noticing sloping, sagging, or bouncy floors, addressing these problems before any new flooring installation is essential for both aesthetics and structural integrity.
Why floors become uneven in older homes
Before tackling repairs, it's helpful to understand why floors become uneven in the first place:
Foundation settlement
Over decades, foundations naturally settle into the ground at different rates. This uneven settling creates slopes and dips throughout the house. In some regions around Summerfield and Greensboro, NC, the clay soil expands and contracts significantly with moisture changes, exacerbating foundation movement.
Structural deterioration
Support beams, floor joists, and subfloors can deteriorate over time due to moisture damage, insect infestation, or simply age. When these structural elements weaken, floors begin to sag or bounce.
Previous renovations
Historic homes often undergo multiple renovations throughout their lifespans. If these updates weren't properly executed, they might have compromised the floor structure or created uneven transitions between rooms.
Water damage
Leaking pipes, flooding, or persistent dampness can cause wood components to warp, rot, or deteriorate, leading to uneven surfaces.
Assessing the severity of your uneven floors
Before beginning repairs, determine how serious your floor issues are:
- Use a level to measure the slope across different areas of your floors
- Check if the unevenness is consistent or confined to specific areas
- Look for visible signs of damage to floor joists or subfloors in accessible areas like basements or crawl spaces
- Note any accompanying issues like sticking doors, cracked walls, or separated moldings
For significant sloping (more than 1-2 inches across a room) or signs of structural issues, consult a structural engineer before proceeding with any repairs or flooring installation.
Solutions for minor unevenness
If your floors have slight dips or slopes but no major structural concerns, these approaches may help:
Self-leveling compound
For minor dips and low spots up to about ¾ inch, self-leveling compound provides an effective solution. This liquid material flows into depressions and creates a level surface as it hardens. It's particularly useful when preparing for new flooring installation in bathrooms, kitchens, or other areas receiving tile or vinyl flooring.
Shimming
For wooden subfloors with minor unevenness, thin wooden shims can be inserted between the subfloor and joists to raise low areas. This technique requires accessing the underside of your floor through a basement or crawl space.
Floor leveling systems
Various leveling systems are available for different flooring types. These typically involve specialized hardware that helps compensate for uneven surfaces during flooring installation.
Addressing major structural issues
For significant unevenness, more substantial interventions may be necessary:
Sister joists
When floor joists have sagged or weakened, installing new joists alongside the existing ones (sistering) can provide additional support. This reinforcement helps correct sagging floors and prevents further deterioration.
Jack posts
In cases where central support beams have settled, adjustable steel jack posts can be installed to gradually lift and re-level the beam. This process requires careful adjustment over time to prevent damage to other structural elements.
Foundation repairs
If unevenness stems from foundation problems, solutions might include mudjacking, installing helical piers, or underpinning. These significant repairs should always be handled by qualified foundation specialists.
Subfloor replacement
Sometimes, the most effective solution is removing and replacing damaged sections of subfloor entirely before proceeding with new flooring installation.
Choosing appropriate flooring for uneven surfaces
Even after leveling efforts, some older homes may retain slight irregularities. Consider these flooring options that work well with somewhat uneven surfaces:
Engineered hardwood
Unlike solid hardwood, engineered products can better accommodate minor inconsistencies while still providing natural wood beauty.
Luxury vinyl plank (LVP)
Modern LVP products offer some flexibility that helps them conform to slightly uneven surfaces while providing excellent durability.
Laminate with robust underlayment
Thick underlayment can help bridge minor irregularities beneath laminate flooring.
Wall-to-wall carpet
Carpet with quality padding can mask minor floor unevenness better than hard surface options.
