Questions
Do you offer regular maintenance plans for residential windows?
Yes, we provide customizable weekly to bi-annual maintenance plans. Many clients pre-pay for six months or a year of service to ensure consistently clean windows without scheduling concerns.
Can you clean windows during Wisconsin winters?
Absolutely. We use anti-freeze solutions and appropriate gear to work year-round. Winter cleaning enhances visibility of snowscapes while maintaining window integrity against harsh weather conditions.
How do you handle furniture near windows?
We work around furniture when possible. For extensive moves, we charge a small fee. Senior citizens receive special consideration, with free minor furniture adjustments as part of our community commitment.
What post-construction cleaning services do you provide?
We specialize in removing construction residues like mortar, paint, and adhesive. Our technicians restore windows to showroom condition using safe methods, making us preferred partners for local builders and contractors.
How does pure water window cleaning work?
Our 5-stage filtration system removes impurities to create ultra-pure water that effectively cleans without residue. This eco-friendly method leaves windows spot-free while protecting surrounding surfaces from chemical exposure.
Do you clean window treatments like blinds and drapes?
We recommend removing decorations beforehand. While we can work around most window treatments, certain blinds require removal for thorough screen cleaning. We protect valuables and ensure meticulous post-cleaning cleanup.
