(3) If a warranty of quality explicitly extends to future performance or duration of any improvement or component of the condominium, the cause of action accrues at the time the breach is discovered or at the end of the period for which the warranty explicitly extends, whichever is earlier.

(4) If a written notice of claim is served under RCW 64.50.020 within the time prescribed for the filing of an action under this chapter, the statutes of limitation in this chapter and any applicable statutes of repose for construction-related claims are tolled until sixty days after the period of time during which the filing of an action is barred under RCW 64.50.020.
