A deep clean in West Palm Beach’s historic districts is a different job from a deep clean in a new condo, and the reason is the age of the housing stock. The El Cid Historic District alone contains 281 historic buildings, most of them sold between 1923 and 1926, and the Flamingo Park Historic Residential District contains another 458. A house that has stood through a century of South Florida humidity and salt air has original tile, plaster, wood and window hardware in it — surfaces that respond badly to the fast, aggressive methods that work fine on a 2019 build. Miami House Cleaning deep cleans start at a flat $256 for a studio under 1,000 sq ft and are priced by square footage above that; call 754-354-6072 for custom pricing on a specific home.
This guide is for owners and long-term renters in El Cid, Flamingo Park, Grandview Heights, Old Northwood and the surrounding West Palm Beach neighborhoods who want to know what a deep clean should actually do in a period home — and, just as importantly, what it should leave alone.
Why the age of the house changes the deep clean
West Palm Beach’s historic residential core is unusually concentrated. Four of its districts are listed on the National Register of Historic Places: El Cid (listed 1995, bounded by Flamingo Drive, South Flagler Drive, Dyer Road and South Dixie Highway), Flamingo Park (2000), Grandview Heights (1999) and Old Northwood (1994). The homes are largely Mediterranean Revival, Mission and Spanish Revival, built in and around the 1920s land boom.
Three practical consequences follow from that, and they drive everything below:
- The surfaces are porous and mostly unsealed. Original terrazzo, 1920s hex and field tile, cement grout, lime plaster and heart-pine floors all absorb liquid. Anything you leave sitting on them, cleaner included, goes in rather than on.
- They are close to the water. El Cid’s eastern boundary is South Flagler Drive, on the Intracoastal. Salt-laden air reaches glass, window hardware and metal fixtures in these blocks year-round.
- The finishes are not replaceable. A dulled patch of original terrazzo or an etched period tile is not a repair; it is a restoration job for a specialist. The cheapest version of this is not to damage it.
Original floors: terrazzo, period tile and heart pine
If your West Palm Beach home still has its original floors, this is the single place where a well-meant DIY deep clean does the most lasting harm. Acidic supermarket cleaners — anything vinegar-based, anything marketed for hard water or soap scum — dull cement terrazzo and etch marble thresholds. On old wood, the damage is the opposite problem: water. Heart pine laid in the 1920s sits over a crawl space or on strapping, and the seams have had a hundred years to open. A wet mop pushes water into those seams, and it comes back as cupping and darkened boards weeks later.
How our crews handle it: pH-neutral products only on terrazzo and stone, damp-not-wet microfiber on original wood, and no acid anywhere near a period threshold. Where a floor is dull, hazed or worn through its finish rather than dirty, we say so instead of scrubbing harder — a dull floor is usually a refinishing question, and we cover that distinction in our guide to floor cleaning versus refinishing. Cleaning is what we do; refinishing, sealing and restoration are not services we offer.
Unsealed grout in an original bathroom
Period bathrooms in these districts often retain their original wall and floor tile with cement grout that has never been sealed, or was sealed decades ago. In a climate where the wet season runs most of the summer, that grout holds moisture, and the grout lines are where discoloration and visible mildew show up first — along with the ceiling above the shower and the back wall of a linen closet in a house with no exhaust fan.
A deep clean removes the visible growth and the soil it feeds on, which reduces what you are exposed to day to day. It is not a medical or remediation service: cleaning does not treat, cure, prevent or diagnose any health condition, and it does not fix the cause. If moisture keeps coming back after a thorough clean — a recurring stain on the same patch of ceiling, a musty smell with no visible source, growth behind or under a finished surface — that is a licensed mold remediation contractor’s job, not a cleaner’s, and we will tell you that rather than keep cleaning the symptom. The US EPA’s guidance on mold is the plain-language starting point if you want to read about the moisture side.
Casement and jalousie windows, and the salt film on the glass
Newer buildings have sliders and fixed glass. A lot of the 1920s stock in Flamingo Park and Grandview Heights has steel casement or jalousie windows instead: hand-cranked, with narrow louvers, hinges and sills that collect a paste of salt, pollen and grit. Ordinary glass cleaner smears that film rather than lifting it, and no vacuum will pull it out of a casement track.
On a deep clean these get worked by hand — louver by louver, tracks and sills included — which is slower than wiping a slider and is one of the honest reasons a period home takes longer than a condo of the same square footage. Glass is also the detail customers notice most. One of our deep-cleaning customers, Tim Duggan in Surfside, had assumed his floor-to-ceiling windows were too much to ask for:
“Perfect in every way… Teresa was an amazing cleaner. They did extra stuff — I really wanted my floor-to-ceiling windows cleaned but thought it was too much to ask, and they did an amazing job on them. I can’t find anything they did not clean.”
— Tim Duggan, verified Google review
Interior and exterior glass is an add-on rather than part of the base deep clean, so ask for it when you call and it gets quoted into the job.
Plaster walls, painted wood trim and picture rails
Lime plaster and the painted wood trim, crown moldings and picture rails common in these homes are not scrubbable the way modern drywall and latex paint are. Plaster chalks and crazes, and old oil-based paint on trim can lift under a magic-eraser-style abrasive pad. Our crews dust high trim dry first, then spot-clean with a mild solution and the least abrasive tool that works, and leave anything that looks like a failing finish alone rather than taking paint off a 1925 molding.
Deep clean or regular clean: which one do you actually need?
The distinction matters here because a deep clean in a period home is a real labor investment, and you should not buy one twice.
- Book a deep clean if it has been six months or more, if you have just bought the house, if grout and baseboards have visible buildup, if the home sat closed through a wet season, or before you start a recurring schedule. It covers baseboards, grout, inside and behind appliances, vents, light fixtures, window tracks, and detailed kitchens and bathrooms. Deep cleans start at $256 for a studio under 1,000 sq ft and are quoted by square footage above that.
- Book regular house cleaning — from $156 for a studio under 1,000 sq ft — to hold the result once the deep clean is done. In a historic home this is the cheaper path by a wide margin, because the slow work is the catch-up, not the maintenance.

What we do not do
Being clear about this saves everyone a wasted visit:
- No junk, debris or haul-away removal. We clean; we do not remove furniture, renovation debris or accumulated belongings. A period home that needs clearing out first should be cleared before we arrive.
- No refinishing, sealing, polishing or restoration of terrazzo, wood or stone.
- No mold remediation and no work inside walls, ducts or under finished surfaces.
- No promises on same-day service. Same-day and next-day slots are sometimes available depending on the schedule — call 754-354-6072 to check.
