Frequently asked questions

Can I install the system myself?

Yes, with the easy to follow instructions that come with the Trex® RainEscape® system, a pair of scissors, utility knife, staple gun and caulking gun are all you need to install the system in one or two hours on most decks.

Can I install this over an existing deck?

Yes, but the existing deck boards must be removed while you install the Trex RainEscape System.

How do Trex RainEscape prices compare to other similar systems?

Although Trex RainEscape is a unique water drainage system it costs less than the nearest competitor.

How durable is the RainEscape System?

Made with rugged plastic and ultra violet inhibitors, the Trex RainEscape system is extremely durable.

How do you clean out the debris?

There should be very little if any debris that enters the system because it has to be small enough to fit through the decking. Small debris simply passes through the system with water. In the rare case that there is some build up, simply remove the piece of decking over the affected area and clean as needed.

Is the Trex RainEscape System affected by freezing temperatures?

If the system is installed correctly any water that is caught drains out through the downspout in a matter of seconds. With no water remaining in the system, freezing is not an issue.

What about snow build-up?

Snow will sit on the decking and, as it melts, will run through the system.

Are leaves a problem?

If leaves and debris accumulate in the troughs, a standard washing or a hard rain will clean out the system.

What if I can’t get the tape to stick?

In areas, such as the perimeter, or surfaces of brick or stucco where the Trex RainEscape tape will not stick, use the Trex RainEscape caulking to adhere the material.

Can I splice the trough material?

NEVER splice trough material. See our instructions for spans that are longer than the trough material. Do not try to repair any damage with the Trex RainEscape tape.
