RV Slide out can leak due to worn out, cracked slide seals which need to be replaced to stop the water leaking in. Ideally, the seals should be replaced every 2 year. Slide out can also leak water when the RV isn’t leveled, this can be rectified by making sure it is properly leveled.
How much does it cost to replace RV slide out seals?
If you wait too long, you could risk damaging the wood frame around your slideout. These repairs can likely be done in one day, and costs can vary widely, depending on size, wear and number of seals. Expect to pay over $1,000 for a full seal replacement.
Can you use WD40 on RV slide out?
WD40 is not really a lubricant. It is WD which = “water displacent.” My slide manufacturer recommends no lubricant…but, if you must, use silicone.
