What is Celtic Rainwater Systems?

Celtic Rainwater Systems is a small gutter and drainage company in Indianapolis, Indiana. Its website gives its mission as protecting homes “from damage caused by rainwater” and says it does so through gutter and drainage services for “properties of all types and sizes”[4]. The business is registered as Celtic Rainwater Systems, LLC, an Indiana limited liability company that business-record aggregators show as formed on 2 March 2022[1]. Its listed address is 8059 Castleton Road, Indianapolis, IN 46250, and its phone number is (317) 450-4648[2].

The company describes itself as “based out of Indianapolis” and says it serves the community “because it is our community too”[4]. Its Nextdoor business page says it serves “Indianapolis and the surrounding areas”[5]. It does not publish a list of towns, so this reference does not supply one; the service area page explains what can and cannot be said.

What services does it offer?

The website groups the work under four headings, and each has its own page here:

  • Gutter installation: new seamless 5-inch, 6-inch and half-round gutters, guard installation, repairs to existing gutters, custom leader heads and scupper boxes, snow bars, and fascia and soffit replacement[6]. See gutter installation.
  • Gutter guards: several guard styles, including a micromesh guard for fine debris and one compatible with copper gutter systems[7]. See gutter guards.
  • Gutter cleaning: cleaning with an inspection and small repairs, offered as an auto-scheduled seasonal maintenance plan[8][4]. See gutter cleaning plans.
  • Drainage: PVC replacement of buried downspout lines, pop-up emitters, exterior sump pumps, exterior and interior French drains and basement sump pumps[9]. See drainage services.

Directory listings on Angi and HomeAdvisor add copper and galvanized gutter installation and repair to that list[10][11]. The company does not publish prices on its website; it offers a free quote or on-site visit through a contact form[2].

Why does rainwater control matter in Indianapolis?

Indianapolis gets a lot of rain. NOAA daily records for Indianapolis International Airport average 43.61 inches a year over 1996 to 2025, with the wettest months in late spring and early summer and about 10.7 days a year bringing an inch or more[12]. At the standard conversion of 0.623 gallons per square foot per inch, a 2,000-square-foot roof sheds roughly 54,000 gallons in an average year[13]. The rainfall data article sets out the month-by-month figures and the method.

Where that water goes is also regulated. Citizens Energy Group, which runs the sanitary sewer system, says downspouts should spill onto the ground at least three feet from the building and must not connect to the sanitary sewer[14], and the city bills a monthly stormwater fee based on hard-surface area[15]. Those rules are covered in downspouts and the sanitary sewer and the stormwater fee article.

How is the company rated?

On 9 November 2026 its Google Business Profile, listed under the category Contractor, showed a 5.0 rating from 137 reviews[3]. Angi and HomeAdvisor each showed 5.0 from nine reviews[10][11], and Nextdoor labelled it a Neighborhood Favorite for 2025[5]. It is not accredited by the Better Business Bureau[16]. The reviews and profiles page lists each profile and what it shows, without quoting individual reviews.

What else does this reference cover?

Beyond the company, the site explains the main rainwater questions an Indianapolis homeowner meets: gutter sizing, grading, French drains, sump pumps, ice dams, rain barrels, ladder safety and hiring a contractor. Each page cites government or code sources first.
