If they're not cleaned every few days, your windows will turn black and begin emitting a high-pitched scream that makes dogs pregnant. Prevent a neighborhood outbreak of puppies with today's Groupon to On The Spot Home Services. This Groupon is valid for homes anywhere in New Jersey. Choose from the following options:

• For $39, you get up to 100 feet of gutter cleaning (up to a $125 value).
• For $59, you get an interior- and exterior-window cleaning for 20 standard nonstorm windows or 10 standard storm windows (up to a $325 value).
• For $150, you get $450 worth of power-washing services.

Since 1987, On The Spot Home Services’ safety-trained and certified crew has meticulously blasted dirt and grime from besmirched windows and gutters. During a thorough gutter cleaning, a sanitary specialist will transform gunked-up gutters into smooth-flowing aquatic thoroughfares to prevent leaks, landscape erosion, rotting fascia, and chipmunk swim meets (additional fees apply for gutter guards). A window cleaning—windowsills and frames are not included; french doors, patio doors, panels, and casements may incur an additional fee—removes pollen, dust, and avian droppings from the interior and exterior panes of standard 20"x30" windows, resulting in a subtle yet dazzling sheen similar to that exhibited by enchanted glass footwear.

Alternatively, power-washing can expunge mold, mildew, algae, and moss from vinyl siding—brick, HardiePlank, aluminum, stone, and stucco siding is an additional cost—through the use of a highly focused stream of water. This Groupon will cover homes up to 1,500 square feet; larger homes will incur an additional expense. On The Spot’s professional dwelling washers are also fully insured and licensed, providing reliable, dependable service and leaving home exteriors sparkling more beautifully than a firefly on prom night.

Though On The Spot Home Services sometimes features a discounted price online, this Groupon still offers the best deal available.
