About i4improvements
i4improvements is a licensed plumbing, renovation, and property management contractor serving Washington D.C., Arlington, Alexandria, Fairfax County, and Montgomery County. We work on historic D.C. rowhouses, custom Northern Virginia homes, and rental properties across the DMV. Our focus is the regulatory complexity of this market — HPRB historic preservation, the Lead Free DC program, Basic Business License compliance, TOPA advisory, and Virginia ADU zoning — paired with the day-to-day craft of getting jobs done on time, on budget, and to code.
Local expertise & compliance
The D.C. metropolitan area has unique property challenges and regulations. We work daily with HPRB guidelines in historic districts, Virginia ADU zoning, the Lead Free DC program, and Basic Business License requirements. Every project is planned for compliance from the start — no surprises, no stop-work orders.
One team, three trades
Because plumbing, renovation, and property management sit under the same roof, we coordinate without subcontractor handoffs. A repipe job feeds into a kitchen remodel; a BBL inspection gets the same crew that handled the underpinning. That continuity is what 4.9 stars across 55 Google reviews reflects.
Quality craft & accountable pricing
We are Bradford White & Rinnai Authorized Installers, fully licensed and insured in D.C. and Virginia. Estimates are free and itemized. We stay current on federal IRA rebates and DCSEU local incentives so homeowners capture every dollar of energy savings they qualify for.
