Condo window cleaning at The Sandcastle I

We clean the inside of every window and slider in your Sandcastle I unit, plus the outside of the balcony and lanai sliders from the deck. We vacuum the door tracks, wipe the sills, and our streak-free guarantee covers each Sandcastle I pane we clean.

The Sandcastle I has Gulf frontage, so salt mist often dries on lanai doors between rains. Upper-floor wind can push it toward the door tracks, and a film left for a season can turn cloudy and become stubborn. Cleaning on a regular plan keeps that buildup light.

Glass on the outside of the tower that can only be reached by rope or swing stage is the association’s contractor’s job. Everything you see from inside your unit and from your balcony is ours.

Field Manual · The Sandcastle I

Sandcastle I: sixteen floors at the south end of Marco’s beach

The Sandcastle I is a 16-floor condominium at 730 S Collier Blvd on Marco Island, one of two Sandcastle buildings that listings group as Sandcastle at Marco Beach; Sandcastle II is at 720 S Collier Blvd. A listing for a unit here gives Gulf frontage and Gulf views and places Sandcastle on the southern end of Marco Island’s beach. That listing names covered parking, tennis, pickleball, an exercise room, a pool and spa, barbecue, bike storage and private beach access, and a realtor page for the Sandcastles lists a similar set. Pet rules differ between sources, so confirm them with the association.

Quick facts for owners (from our tower list and realtor listings)

  • Address: 730 S Collier Blvd, Marco Island
  • Sixteen floors
  • Part of Sandcastle at Marco Beach, with Sandcastle II at 720 S Collier Blvd
  • Gulf frontage at the southern end of the beach, per one listing
  • Pool and spa, exercise room, tennis, pickleball, barbecue, private beach access
  • Covered parking, per one listing

Two buildings, one schedule

Sandcastle I and Sandcastle II share a name and, per listings, a similar list of amenities, so the two addresses are easy to mix up. If you own in Sandcastle I, give us the building number with your unit so the crew goes to 730, not 720. If a neighbor in either building wants a visit, we can often plan both on the same day.

Gulf frontage on the south beach

One listing places Sandcastle at the southern end of Marco Island’s beach. A Gulf-front tower there often takes salt on onshore breezes, and it dries into a haze on lanai doors. We rinse salt away with plenty of water before washing, because rubbing dry crystals across the glass can leave fine scratches.

Low floors and high floors

One listing describes a unit with no need for the elevator to reach the pool or beach, so some homes sit close to ground level. Lower units often collect more blown sand in the tracks, while upper floors often take more wind. We adjust the visit to the floor: more track and sill work below, more edge drying and windward-first sequencing above.

Private beach access and the tracks

Listings mention private beach access. Sand comes back in on feet, chairs and towels, and lanai door tracks often hold more of it than owners expect. We vacuum the channel, brush packed grit loose from the corners, then wipe the rails. A clean track often helps the door roll more easily.

Pool, spa and courts

A listing names a pool and spa, tennis and pickleball. After time outdoors, sunscreen and damp hands often leave prints near slider handles. We hand-clean around each handle first, then wash the whole pane, so greasy spots do not smear across freshly cleaned glass.

Covered parking and arrival

One listing mentions covered parking at the building. Ask management where contractors should park and which entrance to use, and we will follow it. Send us your unit number and the building number, and tell the office our visit date. Our insurance certificate goes to management before the first appointment.

Storage and the lanai

The same listing names bike storage and storage among the amenities. Moving bikes, chairs and umbrellas off the lanai before a visit lets us reach the full width of each slider and any railing glass. If gear stays out, we move it carefully and set it back where we found it.

Haze or etching? How we check

Salt film and mineral spots usually lift with washing. Glass that has been neglected for a long time can show a cloudy patch that stays after cleaning. Before quoting extra work, we test a small corner and show you the result. If a pane looks etched rather than dirty, we tell you plainly so you can decide what to do with the association.

Seasonal owners and listing photos

If you close the unit for summer, a visit before you leave removes salt before months of heat, and another before you return makes the first evening brighter. If you plan to sell, schedule cleaning a day or two before photos, since the Gulf view leads the listings we found here.

What we cover at Sandcastle I

The inside of every window and slider. The outside of the lanai and balcony doors, worked from the deck, plus railing glass reachable from there. We wipe tracks, sills and frames, and wash screens if you ask. Glass reachable only from outside the tower is left to the contractor the association hires for rope or lift work.
