Heriz and Serapi rug cleaning on Long Island

Heriz rugs are the big, heavy, geometric rugs with the angular medallion, and they are built to be walked on for a century. They hold more dry soil than any other Persian rug, they curl at the sides, and they take longest to dry. At our Farmingdale plant they are dusted hard, washed cold, spun well and dried flat under weight. Free pickup across Nassau and Suffolk.

At Green Choice Oriental Rug Cleaning Long Island, every Heriz rug is cleaned inside our own plant at 44 Executive Blvd, Farmingdale, never on your floor, and never sent out to anyone else.

How to recognize a Heriz

Heriz is a district of villages northeast of Tabriz. The rugs are coarsely knotted, 40 to 100 symmetric knots per square inch, on a heavy cotton foundation with a thick, hard‑wearing wool pile. The design is unmistakable: a large angular medallion with stepped outlines, corner pieces, and stylized geometric flowers, in brick red, rust, navy, ivory and a little green. Older, softer‑colored examples are sold as Serapi; Gorevan and Ahar are related weaves. Room sizes are standard, 8×11 to 12×15, and the rugs weigh a great deal.

Heriz rugs are the Persian rug of choice for Long Island family rooms and high‑traffic halls, in Huntington, Northport, Garden City, Manhasset, Sayville and East Hampton, precisely because they are so durable. The trade‑off is that they are also the dirtiest rugs we receive.

What we find on Heriz rugs

Pounds of soil. The open, coarse weave lets grit straight through to the foundation. A 9×12 Heriz from a Long Island family room is often five to seven pounds lighter after dusting.

Curling sides. Heriz selvedges are wrapped tightly and the rug curls under along both long sides. Washing relaxes it; drying flat under weight and, if needed, a curl treatment fixes it.

Slow drying and mildew risk. The heavy foundation holds water. A Heriz "cleaned" on a floor stays damp for days and can mildew or dry‑rot at the back. A centrifuge and a drying room are essential.

Worn ends and lost knots. The coarse ends unravel quickly once the end finish goes.

Pet urine, which the open weave takes straight to the foundation.

How Green Choice cleans a Heriz at 44 Executive Blvd

A Heriz takes the most aggressive dusting and the longest extraction and drying of any Persian rug, and it is dried flat under weight to remove curl.

1

Inspection and dye test

Knot, condition, ends and curl documented. Rust and red tested. UV check. Firm price approved.

2

Hard dusting, both directions

Multiple firm passes face‑down through the dusting machine, turned end for end, until the soil stops coming. This stage takes longer on a Heriz than on any other rug.

3

Cold immersion wash

Submerged in cool water with a neutral wool solution, brushed with the pile. The heavy foundation is allowed a longer soak so the wash reaches it. Urine rugs soaked first.

4

Rinse until clear

Extended flushing; the thick foundation holds detergent and needs more rinse water than a fine rug.

5

Long centrifuge and flat dry under weight

Spun longer than a fine rug to pull water out of the heavy foundation, then dried flat with the curled sides weighted so the rug dries straight. Ends dressed.

Heriz repairs

  • Curl correction along the sides.
  • End stopping and fringe rebuilding.
  • Selvedge rewrapping in heavy wool.
  • Reweaving in coarse matched wool.
  • Dense felt padding, which a heavy Heriz needs to lie flat on hardwood.

Heriz rug cleaning questions

Why is a Heriz so dirty inside?

The coarse, open weave lets sand fall straight through the pile to the foundation, where a vacuum never reaches. Only dusting from the back removes it, and a Heriz releases more than any other Persian rug.

Will washing fix the curled edges?

Washing relaxes the wrap and drying flat under weight sets it straight. Rugs that curl again get a curl treatment along the selvedge.

How long does a Heriz take to dry?

In the drying room, about two days after the centrifuge. On a floor at home, a week or more, which is why floor cleaning risks mildew and rot.

How much does Heriz cleaning cost?

$4 to $6 per square foot, about $430 to $650 for a 9×12.

Do you pick up heavy rugs in the Hamptons?

Yes. Two technicians collect on the weekly East End route.
