Look beyond the surface

Better siding starts
with a better wall plan.

A new exterior is more than a color choice. Water can reach the wall at windows, roof edges, balconies and penetrations. Covering the surface without understanding those details can leave the original problem in place.

Start with a condition record for each building and elevation. Then define the investigation, the repair assumptions and the inspection points before bids go out.

  1. 01Record visible damage and recurring leaks.
  2. 02Clarify flashing, drainage and material transitions.
  3. 03Agree how concealed repairs will be priced and approved.

A better way to compare

Know what’s included.
Know what’s still open.

Two siding bids can look similar and cover very different work. A lower price may omit access equipment, damaged sheathing, window flashing or daily resident protection.

Our comparison tool separates confirmed scope from unknowns. Use your own proposal amounts and adjustments to see where the numbers line up—and where a contractor still needs to answer.

A known exclusion can be priced. An unknown needs an answer. Keep them separate before you compare totals.

Local details that change the plan

St. Louis is more
than one permit office.

Your building’s address, construction and ownership structure matter more than a general answer for “the metro.”

City, County or municipality?

Determine who reviews the exact property. In contracting municipalities, County building review and local zoning can be separate steps. Describe the proposed material, building use and any wall changes when asking about permits.

Check the approval pathway ↗

Historic exterior restrictions

Check district and landmark status before settling on a replacement material or profile. A permit exemption does not settle whether the exterior alteration meets preservation requirements.

Plan for historic review ↗

Association responsibility

A condo declaration determines key exterior responsibilities and cost allocations. Formation date and applicable Missouri provisions also matter. Read those documents before promising a particular vote or assessment method.

Work through board approvals ↗

Start with the City building permit guidance, Cultural Resources Office and Missouri condominium law applicability. Confirm the requirements for your address and scope.

Build your project brief ↗
How much does multifamily siding replacement cost in St. Louis?

A useful budget starts with measured wall area and a defined scope. Removal, access, trim, flashing, concealed damage and occupied-building logistics can change the total. Our cost guide explains the calculation without presenting made-up local averages.

Can a community replace siding in phases?

Phasing can help with cash flow and access, but the design must resolve temporary weather protection, color availability, repeated mobilization and unfinished transitions. Compare the full-project and phased scopes before deciding.

Does a St. Louis siding project need a permit?

Check the exact address, building use, cladding material and work scope. City, County and municipal requirements differ. Historic review can be a separate step, and a narrow replacement exemption should not be assumed to cover every apartment or condo project.

How do I know whether to repair or replace?

Document the extent and cause of damage first. A localized, accessible defect may support a repair; repeated leakage, widespread deterioration or unresolved details may require investigation and a broader scope. A surface photo alone cannot confirm concealed conditions.
