Post-Construction Deep Clean — 4,500 sq ft New Build in Middletown, DE
A custom home builder in Middletown needed a 4,500 sq ft new construction move-in ready for the buyer's closing date. Drywall dust coated every surface, adhesives remained on windows, and the HVAC system had circulated construction particulates throughout.
The Challenge
The buyer's closing was in 3 days. The builder had attempted cleanup with a standard crew, but drywall dust remained on every surface — visible on dark furniture and causing respiratory irritation. The HVAC system was actively circulating particulates.
Our Solution
Our team deployed a 4-person crew with industrial HEPA vacuums and HEPA air scrubbers. Stage 1: dry particulate removal from all surfaces including walls, ceilings, and ductwork. Stage 2: encrusted residue removal using pH-neutral drywall cleaner and damp microfiber. Stage 3: 48-hour continuous HEPA air scrubbing.
The Outcome
The home passed the buyer's pre-closing inspection with zero dust-related complaints. The builder now uses Impress Service for all Middletown and Bear new construction projects — a partnership spanning 50+ homes.
Airbnb Turnover Optimization — 12-Property Portfolio in Rehoboth Beach, DE
A Rehoboth Beach property manager overseeing 12 short-term rentals was losing bookings due to inconsistent turnover quality. Guest ratings averaged 4.3 stars with frequent complaints about sand residue, stale linens, and missed staging details.
The Challenge
The property manager struggled with multiple independent cleaners who had varying standards. Saturday-to-Saturday turnover schedules left no margin for error. Guest reviews cited sand in bedding, dusty surfaces, and lack of "wow factor" on arrival.
Our Solution
We consolidated all 12 properties under a single Impress Service team with a dedicated coastal turnover protocol. Each turnover includes: HEPA sand extraction, premium linen refresh, supply restocking, staging with seasonal décor, and photo-verified quality reports sent to the property manager before each guest arrival.
The Outcome
Within 8 weeks, average guest ratings rose from 4.3 to 4.9 stars. Occupancy rates increased 18% as algorithmic visibility improved with higher ratings. The property manager now commands 15% higher nightly rates based on consistent 5-star guest experiences.
Historic Victorian Restoration — 1890s Home in Lewes, DE
A new homeowner purchased an 1890s Victorian in historic downtown Lewes and needed a deep clean that would remove decades of grime without damaging the original shellac woodwork, hand-carved trim, and period hardware.
The Challenge
The home had been unoccupied for 14 months. Dust had settled on every surface, moisture had promoted mold growth in the basement, and the previous owner had used inappropriate commercial cleaners that left residue on the historic wood trim. The buyer was terrified of causing irreversible damage.
Our Solution
Our historic preservation-trained team conducted material analysis on the woodwork, confirming original shellac finish. We used pH-neutral cleansers (pH 7.0) paired with microfiber technology — mechanical cleaning action without chemical aggression. Gilded details received soft-bristle brush treatment with distilled water. Basement mold was treated with antimicrobial solution safe for historic foundations.
The Outcome
All original finishes were preserved with zero damage. The homeowner referred us to three additional Lewes Historic District properties. Our historic cleaning protocol is now documented for use across all pre-1950 Delaware properties we service.
Commercial Office Janitorial — 15,000 sq ft Medical Office in Dover, DE
A Dover medical practice needed a commercial cleaning service that could meet healthcare facility sanitation standards while working around patient hours. Their previous service failed two consecutive OSHA-adjacent inspections.
The Challenge
Medical office cleaning requires EPA-registered hospital-grade disinfectants with proper dwell times — something the previous service routinely skipped. High-touch surfaces in exam rooms, waiting areas, and restrooms needed daily disinfection. The practice also required documentation for compliance audits.
Our Solution
We implemented a medical-grade protocol: nightly disinfection of all high-touch surfaces using hypochlorous acid solutions (bactericidal/virucidal in 30 seconds), proper dwell time documentation, MERV 13+ HVAC filter coordination, and touchless restroom dispensers. We provide monthly compliance reports for the practice's audit files.
The Outcome
The practice has passed every inspection since switching to Impress Service — 18 consecutive months. Patient satisfaction scores related to facility cleanliness improved by 23%. The practice referred us to two neighboring medical offices in the same Dover professional building.
