Call 215-694-5046 to schedule an appointment with Ron the Rail-Guy. I'll walk you through all your options, ask you some questions, you ask me some questions, then, I'll prepare a proposal, email it to you, (usually next day), you say ok, when do we start, and we go from there. I'm based in the FoxChase area of Philadelphia, but I service from Princeton, to the MainLine, and from Doylestown to the Jersey Shore, and every town in between.
Most jobs can be started within 2-5 weeks, depending largely upon whether you want something that's in stock, or if you want something that's a little more custom. Lead time is also effected by time of year, obviously. Oct-Dec tends to be my busiest time, because many folks want to spruce up their houses for the inevitable holiday parties. Jan-Mar is historically slow, so you tend to get quicker service, just because there are less jobs on the schedule.
This is a brand-new home, obviously, but I also replace many old, tired, ugly, creaky, Stairs and Handrails, and make them better than new.
Call/Text 215-694-5046, or email me at firstname.lastname@example.org to schedule your appointment today, and enjoy your new Stair and Handrail, very soon.
