Do we have to have our carpets professionally cleaned if we signed a carpet waiver 5yrs ago when we moved in?

Did you include the fact they were in poor condition when you moved in on your lease? Typically, walk throughs are done and noted so the landlord doesn't charge you for existing damage.  Further, reasonable wear and tear on things like carpet are items that the landlord can charge you for cleaning.  If he has to replace them due to your damage, and not just cumulative damage, you may be held liable for the whole amount.  This is the reason behind security deposits.  Now, if it was regular wear and tear, he may charge you a small amount and will have to eat the rest to replace the carpeting.  You are entitled to an itemized list of expenses taken out of your security deposit upon moving out.  The list must be provided to you within 14 days in your State. See the following: RCW 59.18.260 If any moneys are paid to the landlord by the tenant as a deposit or as security for performance of the tenant's obligations in a lease or rental agreement, the lease or rental agreement shall be in writing and shall include the terms and conditions under which the deposit or portion thereof may be withheld by the landlord upon termination of the lease or rental agreement. If all or part of the deposit may be withheld to indemnify the landlord for damages to the premises for which the tenant is responsible, the rental agreement shall be in writing and shall so specify. No deposit may be collected by a landlord unless the rental agreement is in writing and a written checklist or statement specifically describing the condition and cleanliness of or existing damages to the premises and furnishings, including, but not limited to, walls, floors, countertops, carpets, drapes, furniture, and appliances, is provided by the landlord to the tenant at the commencement of the tenancy. The checklist or statement shall be signed and dated by the landlord and the tenant, and the tenant shall be provided with a copy of the signed checklist or statement. No such deposit shall be withheld on account of normal wear and tear resulting from ordinary use of the premises. [1983 c 264 § 6; 1973 1st ex.s. c 207 § 26.] RCW 59.18.270 All moneys paid to the landlord by the tenant as a deposit as security for performance of the tenant's obligations in a lease or rental agreement shall promptly be deposited by the landlord in a trust account, maintained by the landlord for the purpose of holding such security deposits for tenants of the landlord, in a financial institution as defined by RCW 30.22.041 or licensed escrow agent located in Washington. Unless otherwise agreed in writing, the landlord shall be entitled to receipt of interest paid on such trust account deposits. The landlord shall provide the tenant with a written receipt for the deposit and shall provide written notice of the name and address and location of the depository and any subsequent change thereof. If during a tenancy the status of landlord is transferred to another, any sums in the deposit trust account affected by such transfer shall simultaneously be transferred to an equivalent trust account of the successor landlord, and the successor landlord shall promptly notify the tenant of the transfer and of the name, address, and location of the new depository. The tenant's claim to any moneys paid under this section shall be prior to that of any creditor of the landlord, including a trustee in bankruptcy or receiver, even if such moneys are commingled. RCW 59.18.280 Within fourteen days after the termination of the rental agreement and vacation of the premises or, if the tenant abandons the premises as defined in RCW 59.18.310, within fourteen days after the landlord learns of the abandonment, the landlord shall give a full and specific statement of the basis for retaining any of the deposit together with the payment of any refund due the tenant under the terms and conditions of the rental agreement. No portion of any deposit shall be withheld on account of wear resulting from ordinary use of the premises. The landlord complies with this section if the required statement or payment, or both, are deposited in the United States mail properly addressed with first-class postage prepaid within the fourteen days.     The notice shall be delivered to the tenant personally or by mail to his last known address. If the landlord fails to give such statement together with any refund due the tenant within the time limits specified above he shall be liable to the tenant for the full amount of the deposit. The landlord is also barred in any action brought by the tenant to recover the deposit from asserting any claim or raising any defense for retaining any of the deposit unless the landlord shows that circumstances beyond the landlord's control prevented the landlord from providing the statement within the fourteen days or that the tenant abandoned the premises as defined in RCW 59.18.310. The court may in its discretion award up to two times the amount of the deposit for the intentional refusal of the landlord to give the statement or refund due. In any action brought by the tenant to recover the deposit, the prevailing party shall additionally be entitled to the cost of suit or arbitration including a reasonable attorney's fee.     Nothing in this chapter shall preclude the landlord from proceeding against, and the landlord shall have the right to proceed against a tenant to recover sums exceeding the amount of the tenant's damage or security deposit for damage to the property for which the tenant is responsible together with reasonable attorney's fees.
