1. A two-part seal for sealing between two surfaces lying generally perpendicular to each other, the seal comprising: a first profile which has a base adapted to be fixed sealingly to a first surface of the two surfaces and an upstand which projects from the base and which defines respective inner and outer opposed surfaces, wherein the upstand comprises two spaced upstanding ribs, one being an inner rib and the other being an outer rib; anda second profile which overlies the upstand of the first profile and which, when viewed in cross-section, comprises inner and outer depending limbs wherein an inner surface of the inner rib of the upstand is slidably engaged by the inner depending limb of the second profile and an outer surface of the outer rib of the upstand is slidably engaged by the outer depending limb of the second profile, wherein at least one of the inner and outer depending limbs of the second profile bears resiliently against a respective surface of the spaced upstanding ribs of the upstand of the first profile in sliding engagement therewith. 2. A seal according to claim 1, wherein both the inner and outer depending limbs of the second profile bear resiliently against the respective surfaces of the spaced upstanding ribs of the upstand of the first profile in sliding engagement therewith. 3. A seal according to claim 1, wherein the free end of one or each inner and outer depending limb of the second profile engages slidably the respective surface of the upstand of the first profile. 4. A seal according to claim 1, wherein the first profile represents a lower profile which can be secured to a generally horizontal surface and the second profile represents an upper profile securable to a wall or other generally vertical support surface, with the upstand of the lower profile projecting upwardly and the inner and outer limbs of the upper profile extending downwardly. 5. A seal according to claim 1, wherein at least the inner depending limb of the second profile is inclined inwardly of the seal. 6. A seal according to claim 1, wherein the inner and outer depending limbs of the second profile are resiliently bendable. 7. A seal according to claim 1, wherein the outer surface of the outer depending limb of the second profile and the outer surface of the upstand of the first profile define at least part of the outer surface of the seal when installed. 8. A seal according to claim 1, wherein the two spaced upstanding ribs are generally parallel with each other. 9. A seal according to claim 1, wherein, in a fully contracted condition of the seal, the two spaced upstanding ribs are inclined away from each other and, in a fully expanded condition of the seal, the two spaced upstanding ribs are generally parallel with each other. 10. A seal according to claim 1, wherein upper regions of the respective inner and outer depending limbs of the second profile are connected integrally together by means of a cover portion wherein a juncture of the cover portion with the upper region of the inner limb is adapted to engage sealingly one of the two surfaces. 11. A seal according to claim 10, wherein the second profile includes a rib upstanding therefrom, and the said rib upstands from the cover portion of the second profile. 12. A seal according to claim 10, wherein the base of the first profile has an inner heel and an outer toe adapted to be adhered sealingly to one of the two surfaces to which the seal can be installed, and wherein the second profile includes a rib upstanding therefrom, and the said rib upstands from the cover portion of the second profile. 13. A seal according to claim 10, wherein the inner and outer depending limbs of the second profile engage the respective inner and outer opposed surfaces of the upstand at different levels, and wherein the second profile includes a rib upstanding therefrom, and the said rib upstands from the cover portion of the second profile. 14. A seal according to claim 1, wherein the base of the first profile has an inner heel and an outer toe adapted to be adhered sealingly to one of the two surfaces to which the seal can be installed. 15. A seal according to claim 1, wherein the inner and outer depending limbs of the second profile engage the respective inner and outer surfaces of the upstand at different levels. 16. A seal according to claim 1, wherein the second profile includes a rib upstanding therefrom. 17. A seal according to claim 1, wherein at least one of the depending limbs of the second profile and the upstand of the first profile comprise complementary engageable barbs for preventing separation of the two profiles when the seal is in its fully expanded condition. 18. A seal according to claim 1, wherein the inner surface of the upstand includes a stop which is engaged by the free end of the inner limb of the second profile when the seal is in its fully contracted condition. 19. A seal according to claim 1, wherein the inner depending limb of the second profile is, when viewed in cross-section, generally linear. 20. A seal according to claim 1, wherein the outer depending limb of the second profile is, when viewed in cross-section, arcuate. 21. A seal according to claim 1, which is securable to one or both of the generally perpendicular surfaces by means of an adhesive, mastic, or double-sided adhesive tape. 22. An installation comprising a pair of generally perpendicular surfaces and a seal according to claim 1 secured between the surfaces in a watertight manner.
