"Chris did an excellent job! My wood deck had 3 old layers of stain and it took longer than expected but Chris was able to successfully remove all of the old stain. During the project Chris found 4 deck boards and 2 rail spindles needed replacing and he helped us out greatly by replacing them at an additional cost after talking to us to save me the time of doing it. The deck was stripped, sealed & re-stained. It looks terrific. Great Job! Chris also talked to us about the mold on our siding and how he can help get that clean too so next year we will have him back to help with the exterior mold removal from the house. Thanks Chris and Keep up the Great Work!"

Window Cleaning FAQs, answered by experts

Yes, professional window cleaning is worth the investment. Regular deep cleanings help keep your windows looking new, extend their lifespan, and boost your home's curb appeal. By removing dirt, dust, and other debris, you can reduce the risk of damage and accelerated wear to window frames and components. It also improves your home’s energy efficiency by keeping insulation and weatherstripping in good working order, potentially lowering your energy bills. Furthermore, annual or bi-annual cleanings can help identify problems like leaks or cracks early, before they escalate into expensive water damage. You can often recuperate the cost of cleaning through energy savings and by avoiding premature window replacement.

To maintain a glass shower door, clean it regularly with a non-abrasive cleaner to prevent soap scum and hard water stains. Using a squeegee after each use is also recommended. Additionally, periodically check for leaks and ensure all hardware remains secure to prevent long-term damage.

Mold on windows forms due to excess moisture from condensation, poor ventilation, or leaks. Cold glass surfaces can attract condensation, especially in winter. High indoor humidity, lack of airflow, or dust accumulation are also contributors. To prevent mold growth, improve ventilation, regularly clean sills, and consider using a dehumidifier or sealing any leaks.

Professionals use pH-balanced solutions, fabric protectors, and safe steam cleaning technology for specific fabrics. These products are designed to break down dirt effectively without leaving residues.

Window cleaning costs around $220, on average, but you could pay anywhere from $150 to $300 or more, depending on the number of windows, how accessible they are, and the type of windows. Some professional window cleaners charge on a per-window basis at around $10 per window, while others provide a single price for your entire home. Either way, more windows will mean higher cleaning costs. Picture windows tend to be the most affordable because they don’t require cleaning of internal components, while double-hung windows and skylights increase your price because they’re more complicated to clean and less accessible.
