Basement Remodeling in Saint Louis Park

Custom basement finishes for Saint Louis Park homes since 1983. Post-war ramblers and split-levels built in the 1950s — one Twin Cities team that checks radon and sump performance before framing a single wall.

Saint Louis Park basements are usually easy to frame. Getting the mechanical and air-quality baseline right is the part that takes real attention.

Saint Louis Park's post-war ramblers and split-levels are similar in structure to the mid-century housing stock in Edina and Bloomington — decent ceiling height, straightforward layouts, and original basement windows that often need to come out before a bedroom conversion. What we pay particular attention to in Saint Louis Park basements is the mechanical baseline: sump performance, radon levels, and rim-joist condition on homes that are now seventy-plus years old and have usually had at least one water event in their history. We test and evaluate that baseline before finalizing a scope, rather than assuming a 1950s basement performs the same as it did when it was built.

  • Full basement finishes — family room, bath, bedrooms, storage

  • Legal bedroom conversions with code-compliant egress windows

  • Radon testing and mitigation system integration where needed

  • Sump pump evaluation and upgrades for aging post-war foundations

  • Wet bars, home offices, and custom built-ins from our cabinet shop

  • Rim-joist insulation and moisture remediation for seventy-plus-year-old construction

Basement Remodeling in Saint Louis Park

What’s included in a Knutson basement remodel

Moisture and envelope — rim-joist spray foam, perimeter drainage review, and a full sump pump evaluation, with particular attention to homes that have had a prior water event, which is common in Saint Louis Park’s post-war housing stock at this age.

Framing and insulation — code-compliant framing and insulation appropriate to the eight-foot ceiling height typical of this era’s ramblers and split-levels.

Code-compliant egress — cutting a new opening into the foundation for a legal bedroom where original basement windows don’t meet current size or sill height requirements.

Radon testing and mitigation — testing current radon levels and integrating a mitigation system into the basement plan where levels warrant it, rather than treating air quality as a separate concern from the remodel itself.

Electrical and HVAC — new circuits, panel evaluation, and supply and return runs sized correctly for the finished space.

Plumbing — bath rough-in, wet-bar plumbing, and a grinder pump where gravity drain isn’t feasible.

Custom built-ins — media walls, home office millwork, and bar cabinetry built in our own shop.

Why Saint Louis Park homeowners choose Knutson

A basement built in the 1950s has had seven decades to develop whatever issues it’s going to develop, and a lot of those issues — a marginal sump, elevated radon, a rim joist that’s never been properly insulated — don’t announce themselves until the space is finished and something starts to smell wrong or test poorly. We evaluate that mechanical baseline as its own step, not an assumption we skip because the framing itself is usually straightforward in this housing stock.

The second reason is what happens once that baseline is solid. Post-war ramblers give us a clean, workable basement to design in, and our cabinet shop builds the bar, office, or media wall to whatever standard the rest of the home has been updated to, so the finished basement doesn’t feel like the oldest part of an otherwise updated house.

  • Yes, and we include that testing as part of the planning phase. If levels warrant it, a mitigation system gets integrated into the basement plan rather than added as an afterthought once finishes are already in place.
  • Many do, simply due to age. We evaluate current sump performance as part of the moisture diagnostic, especially in homes that have had a prior water event, which is common in housing stock this age.
  • Yes, if we can create a code-compliant egress opening. Original basement windows in this era's homes typically don't meet current size or sill height requirements, so this usually means cutting a new opening into the foundation.
  • A straightforward first-time finish runs $45,000 to $75,000. A finished basement with a full bath and legal bedroom typically lands between $70,000 and $130,000, with radon mitigation or sump upgrades sometimes adding to either range.
  • Planning and selections typically run four to eight weeks, followed by eight to fourteen weeks on site, depending on scope and any mechanical upgrades needed.
